A fake arm cast can be useful in many situations. Maybe you want to prank a friend, or you need it for a costume. You can use a simple method, such as using toilet paper, or a more complicated one, sewing recyclable chalk with a sewing machine, to make yourself a fake chalk.
Steps
Method 1 of 3: With toilet paper
Step 1. Use a washable marker to mark the outlines of the chalk
Decide how much you want it to cover your arm.
- For this type, it is best not to go beyond the elbow.
- It will look more like an old plaster model, rather than one of today's fiberglass structures.
Step 2. Wrap two layers of toilet paper around the bottom of your arm
Starting just below the drawn line, start wrapping the paper around your arm in two layers. Tear off the paper.
At this point, don't cover your hand. Focus on the part of the arm below the wrist
Step 3. Wet the paper
Keep your arm under the water for a few seconds, wetting the paper well.
Step 4. Squeeze the water
Press the paper against the skin, draining the water.
It doesn't matter if creases or tears are formed. You will cover that layer with more toilet paper
Step 5. Add a couple more layers of paper
Wrap it around the same area as your arm.
Step 6. Wet the paper again
Keep your arm underwater for a few more seconds to wet the toilet paper.
Step 7. Squeeze the water again
Drain the water, pushing the paper against your arm.
Step 8. Repeat the process
Keep adding paper until you get a thick layer at the bottom of your arm.
Step 9. Start wrapping your hand
Connecting it to the rest of the chalk, wrap the paper around your hand, passing over and under your thumb.
Step 10. Repeat the same procedure above
Add layers, wetting them as you go. Be sure to press the paper against your arm to drain excess water.
Step 11. Let the plaster dry
You can rest your arm on a towel or pillow to let the cast dry.
Otherwise, try a hair dryer
Method 2 of 3: With a stocking, gauze, and tape
Step 1. Use a white sock
Cut off the ankle. Cut out a triangle at the ankle, leaving it attached on the upper side.
- If the sock is long enough, you can cut off the whole foot. Basically, you want to create a tube that covers your entire arm. By cutting out just the heel, you create a tube that lies flat on your arm.
- Use a sock that you no longer use, as you will make it unusable.
Step 2. Cut out the toes from the sock
Cut off the end of the sock leaving an even side.
Step 3. Cut a hole for the thumb
Leaving about 5 cm at the bottom of the tube, cut out a small section for the thumb.
Cut a semicircle into the folded sock with sharp scissors, making a hole for the thumb
Step 4. Put the sock on your arm
Pull the sock according to how far you want to cover your arm. If it's too long, cut off the excess to make it shorter. However, it is good to leave some at the end to fold the gauze.
Step 5. Wrap the arm with self-adhesive gauze
Starting from the bottom, wrap your arm with gauze. Leave some space at the bottom of the sock to fold the gauze. Overlap the layers. When you reach your hand, wrap over and under your thumb, leaving your fingers free.
Don't over tighten, or you'll block circulation
Step 6. Fold the sock over the gauze
Fold the ends of the sock over the gauze.
This step isn't critical, but it will make the ends look tidier
Step 7. Use colored tape to wrap around the arm
Starting with the folded end at the bottom, wrap some colored ribbon around your arm, overlapping as you go. You can use masking tape or masking tape.
- Make sure you don't over tighten. You don't want to cut off the circulation.
- Use small pieces to make the job easier. Use about 12 inches of duct tape at a time so it doesn't fold back on itself.
- You can use sports tapes instead of scotch tape.
Step 8. Trim the excess tape at the thumb level
If the edge of the tape builds up too much on your thumb, carefully trim the edges.
Method 3 of 3: With a sewing machine
Step 1. Calculate the length and width of the arm
Start where you want the cast to start, at the bottom of the arm, and measure to the end of the palm. Make a note of the number.
Step 2. Measure your arm circumference
Wrap a measuring tape around the thickest part of your arm. Write down the number. Wrap the measuring tape around your hand just below the thumb. Write down the number.
Add about 5cm to each measurement for overlap
Step 3. Measure two pieces of flannel
Use the length and circumference of your arm to cut out a piece of flannel.
Fold each side from the largest to the smallest circumference
Step 4. Cut out two pieces of flannel according to your measurements
Also cut out the cotton batting for the center, to the same size.
Step 5. Check that the cast fits comfortably on your arm
Put a piece of flannel around your arm. Make sure it overlaps about 3 cm on each side at its thickest point.
The part at the end of the hand will then have a hole for your thumb
Step 6. Cut the tights into 2-3cm strips
Use an old pair of tights. You can use colored or white ones, as you like.
Step 7. Assemble the layers
Put a piece of flannel on the bottom, the batting in the middle and a piece of flannel on top. Arrange the strips of pantyhose on top.
The flannel strips should overlap each other and zigzag across the cast. They should also be arranged in width and not just in length
Step 8. Sew the strips
Proceed along the edges of the strips to sew them. You can use a plain or zigzag stitch.
You can use thread in the same color as the tights, or a complementary color
Step 9. Cut a hole for the thumb
Fold the chalk in half lengthwise. About 3 cm from the top, cut a round hole large enough to fit your thumb with scissors.
Step 10. Sew around the chalk and the thumb hole
Using a zigzag stitch, swipe along the edges of the chalk and around the thumb hole.
Step 11. Sew Velcro strips to the chalk
On the two long sides, sew matching Velcro strips.
Step 12. Wrap the cast around your arm
Attach it with velcro.
