The easiest way to make a cone is to start with a semicircle and then overlap the straight sides until it forms a cone. However, if you want to be more specific, you should cut it in the form of a circle. Once you know how to make a regular cone, try experimenting with other materials, such as sheet plastic.
Step
Method 1 of 4: Making a Simple Paper Cone
Step 1. Determine the height of the cone, then multiply the number
For example, if you want to make a cone 30 cm high, that means it is 60 cm long.
Step 2. Draw a semi-circle based on the doubled height
Use the previously doubled size as the length of the semicircle (aka its diameter). For example, for a cone 30 cm high, the length of the semicircle required is 60 cm.
- Draw a half circle using a compass or pencil tied to the end of the thread. If it's the right size, you can also use a plate or other round object.
- Align the straight side of the semicircle with the edge of the paper so you don't have to cut or draw too much.
- You can also use paper, cardboard, cloth, cardboard, cork, or even a thin sheet of plastic.
Step 3. Cut the circle in half with scissors
Since the straight side of the semicircle is aligned with the edge of the paper, you'll only need to cut off the curved part. This will be the edge of the base of the cone so cut it as neatly as possible. Tip: turn the material and not the scissors when cutting.
You don't need to make extra tongues or labels as the straight sides will overlap to form a cone
Step 4. Overlap the straight sides to get the desired cone size
Find the midpoint of the straight side of the semicircle. Bring the two ends of the straight sides of the semicircle to that point, and overlap them. Slide the two ends past each other until you get the desired cone size.
- The more overlapping parts, the smaller the cone will be.
- If the overlapping parts are slightly overlapping, the cone will widen.
Step 5. Glue along the meeting part of the straight sides of the cone
The finished result will be neater if you glue the cones with glue, tape or a stapler. If you're using masking tape, attach it to the inside and outside of the cone so it doesn't open.
You can use a glue stick, but liquid glue will hold the cone better. Temporarily secure the cone joint with masking tape until the glue dries. If so, remove the tape
Method 2 of 4: Making an Icing Cone
Step 1. Cut the parchment paper into a 20 x 40 cm rectangle
This is a standard size cake decorating cone. For other cone sizes, make the length twice the width/height, plus 2.5 cm (eg 15 cm x 32.5 cm).
- You can use wax paper instead of parchment.
- This method can be used to make cones from printing paper or construction paper.
Step 2. Cut the rectangle diagonally to make 2 triangles
Place a ruler connecting the top right corner with the bottom left corner of the rectangle. Cut along the ruler using a cutter knife. You can also draw a line along the ruler with a pen, and then cut the guide line with scissors.
Save one triangle for the icing cone, and set the other triangle aside for another project
Step 3. Roll the short side of the triangle towards the bottom side
Think of it like rolling paper into a tube. The back of the paper will touch the front. The high side of the triangle will be the top of the cone.
- As the short edge gets closer to the bottom of the paper, the cone will get wider.
- As the short side gets further away from the bottom side, the cone gets narrower.
Step 4. Continue rolling the paper into a cone
When the paper is rolled up, adjust the angle so that the tip of the triangle points to the wide part (base) of the cone. This end will be folded into the cone so that it can be held.
Set the tip of the cone to be pointed. Later, this pointed end will be cut before being used to pour cake icing
Step 5. Fold the ends of the paper into a cone
After you finish wrapping the cone, the corners of the paper will stick out through the edges of the base of the cone. Fold this corner into the cone so that everything is held in place.
Step 6. Fill the cone with icing or melted chocolate
Flip the cone over so that the pointed end is down. Fill the cone through its wide opening with melted chocolate or icing, leaving 2.5-4 cm of space.
Skip this step if the cone will not be used to pour the icing
Step 7. Fold the edges of the cone twice to seal it
If you no Using a cone to pour the icing, cut the base to make it upright. In this case, the cone will need to be glued together with tape, glue, or a stapler.
- The icing cone does not need to be glued. Instead, fold the opening several times to the height of the filling to seal the cone.
- Test the icing penung cone. If the icing or chocolate doesn't come off the end of the cone, cut it off with scissors.
Method 3 of 4: Creating Custom-Sized Cones
Step 1. Determine the height of the cone
The height of the cone determines the radius of the circle that needs to be drawn. The radius is the distance between the center of the circle and its outer edge. Simply put, the radius is half the diameter.
For example, if the desired height of the cone is 15 cm, the radius is also 15 cm
Step 2. Draw a circle using the radius of the cone as the height
Circles are easiest to draw using a compass. You can also use a plate, bowl, or other round object of a suitable diameter and trace it using a pen or pencil.
- For example, if you want to make a 15 cm high cone, use a 30 cm diameter plate to trace.
- Circles can be drawn on any rigid sheet, such as paper, cardboard, craft cork, cloth, plastic sheet, or thin metal.
Step 3. Cut the circle
The tool used depends on the sheet material used. You can use regular scissors to cut paper, plastic, and fabric, while metallic materials require metal scissors.
Be careful when cutting metal as it is very sharp
Step 4. Mark the center of the circle
Fold the circle in half horizontally and close the folds together. Open the circle, then fold it back vertically and close the folds together. Once again open the circle, and mark the point of intersection of the folds in the center of the circle with a pen or pencil.
If the material doesn't fold well, draw an X in the center of the circle, then make a small mark in the center of the X
Step 5. Cut straight from the edge of the circle to the mark made
Think of it like cutting a cake or pie. The larger the cut circle, the narrower the cone. About circle should be enough; overlap the two straight cut edges on the circle to get the desired cone size.
- If you like the mathematical approach, find the circumference of the base of the cone. This is the remaining circumference of the circle after the net is cut.
- If you're using the circumference of a cone, add 1-2.5 cm to the total size so that there is an overlap that can be glued together.
Step 6. Overlap the two straight sides until you get the desired cone size
Join the two straight sides of the former cut of the circle until they touch each other. Then, overlap until the cone is the size you want.
- The more overlapping parts, the narrower the cone will get, and vice versa.
- Make sure the pencil or pen mark you make is in the cone.
Step 7. Glue the edges with tape or glue
To be practical, you can use tape to glue the overlapping parts. For a neater look, lift the overlapping side on top, coat the bottom with glue, then press the two halves together so they overlap again. You can use glue sticks or liquid. Stick the tape on the cone, then remove it when it's dry.
- If you are using cloth, plastic, or metal, use hot glue. Factory glue can also be used to glue the cork.
- If you know how to weld, try covering the metal cone.
Method 4 of 4: Sewing Fabric Cones
Step 1. Cut two 1/3 circles from the cotton fabric
A circle is between circle and circle. The length of the straight side will be the height of the cone. One part will form the inner layer while the other will form the outer surface of the cone. Fabric colors can be matched or matched.
- For example, you could use one patterned cotton fabric and one solid colored fabric.
- To make a narrower cone, cut two pieces of circle.
- If you plan to wash the cones, wash, dry, and iron the fabric first.
Step 2. Cut the foam stabilizer to match the shape of the fabric
Use one of the circle fabrics to trace on the cork stabilizer, before cutting. You only need one cork stabilizer. In order not to be thick, cut 1.5 cm smaller than the shape of the fabric.
- Foam stabilizers have a similar appearance to craft felt, but are stiffer. This material is sometimes labeled “fusible foam”.
- If you can't find a foam stabilizer, replace it with two sheets of fusible interfacing.
Step 3. Iron the foam stabilizer on the wrong side of the outer fabric
If you didn't purchase an ironed-type stabilizer foam, secure it with fabric adhesive spray. Spray as close to the center as possible.
- If you are using fusible interfacing, iron each back (wrong side) of circle each.
- Fusible foam and fusible interfacing have both rough and smooth sides. The rough side is the adhesive side that will be attached to the fabric.
- Read the instructions that came with the product. Each brand has slightly different guidelines.
Step 4. Sew the curved edges with the correct side facing in
Gather the fabrics so that the right side is facing in and the wrong side (interfacing side) is facing out. Sew along the curved edge using a straight stitch and leave 0.5 cm.
- Be careful not to sew on the foam stabilizer or interfacing. If it's too late, carefully cut or tear the residue sticking out of the seam.
- You can use pins to secure the fabric, but be sure to remove them when sewing.
Step 5. Separate the inner and outer layers, then fold them in half to their length
Separate the cones first so that you get a diamond shape. Next, fold this diamond shape in half according to its length. Make sure the wrong side (with the interfacing) is facing out, and place pins along the straight side to secure it.
Do not fold or iron the fabric. Straight sides should be parallel
Step 6. Sew the straight side on the outer seam, starting at the center seam
Don't sew the inner lining just yet. Look for the center joint in the folded section first, just between the inner and outer layers. Place it under the foot of the sewing machine, then, sew to the end of the cone using a straight stitch and leave 0.5 cm.
- Backstitch at the beginning and end of the stitch. This is where you turn the sewing machine over for a few stitches.
- By starting at the center seam, you make sure everything is aligned and neat.
Step 7. Sew the straight side of the inner seam while leaving the rest to turn
Find the junction between the inner and outer layers. Place it under the foot of the sewing machine, and sew along the straight side of the inner lining. Use straight stitches and leave 0.5 cm. When halfway, leave a distance of 10-12, 5 cm to turn.
- Backstitch on both sides of the slit so that the stitches don't separate when the fabric is turned over.
- If the cone is 15 cm or less, the gap that needs to be made is 5-7.5 cm long.
Step 8. Flip the fabric through the slit so that the right side is facing out
Insert your fingers through the slit and pinch the outer (not inner) layers of the cone. Gently pull the fabric through the slit until you get a double-ended cone shape.
For now, you don't have to worry about the neatness of the cone tip
Step 9. Sew the slit until it is closed
Make straight stitches using a sewing machine and leave a distance of 0.5 cm and match the color of the thread. You can also sew it manually using ladder stitch.
- Make sure the edge of the hem is folded into the slit first. It's best if the stitches look as straight and neat as possible.
- If you're using a sewing machine, start with the seam where the outer layer is, and finish the stitch at the bottom end of the inner layer.
Step 10. Slip the inner layer into the cone
Take the inner side of the cone and tuck it towards the outer side of the cone. Use a blunt-tipped tool such as a knitting needle or chopsticks to help push it into a cone.
Step 11. Iron the hem for a neater look
This step is not mandatory, but will add to the tidiness of your finished product. Do not press the cone until it is flat. Lay the cone sideways, then insert the iron into it. Press the iron for a few seconds, then turn the cone and press again.
Continue twisting and pressing the cone until the entire hem is ironed
Tips
- Try to make the curved part of the cone as neat as possible so that the base of the cone can be evenly distributed.
- To make a full cone, trace the base of the cone onto the rest of the material, then cut out the circle. Glue the circle using glue or tape so that it becomes the base of the cone.
