How to make cosplay claws?

Materials and Tools

• 2mm high-density EVA foam
• Craft knife or scissors
• Heat gun
• Contact adhesive
• Gesso or flexi filler
• Sandpaper (600 grit)
• Paint-on primer (e.g., Flex Bond or Hex Flex)
• Spray primer (optional)
• Acrylic paint or nail polish for decoration
• Belt punch or hole puncher
• Paper brads, fasteners, or rivets
• Marking tools (pen, pencil, or white pen for dark foam)
• Ruler
• Optional: 3D printer or clay for pattern creation

Creating the Pattern

1. Using a pre-made pattern: Websites like kinpatsucosplay offer digital downloads of claw patterns. These are great for beginners or those short on time.

2. 3D printing: If you have access to a 3D printer, you can create a 3D model of the claw and print it. This method allows for precise customization.

3. Clay sculpting: Sculpt the claw shape using clay, then create a pattern from the sculpture.

4. Paper mock-up: Create a basic shape using paper to test the size and fit on your hand.

1. If using a 3D print or clay sculpture, cover it with tape.
2. Draw lines on the tape to indicate where the claw pieces will be separated.
3. Carefully cut along these lines and remove the tape pieces.
4. Lay the tape pieces onto paper to create a flat pattern.
5. Scan or trace these pieces into a digital format using software like Adobe Illustrator or Affinity Designer.
6. Print out the final pattern and cut out the pieces.

Cutting and Shaping the Foam

1. Trace the pattern pieces onto 2mm high-density EVA foam. If using black foam, a white pen can help make the lines more visible.
2. Carefully cut out the foam pieces using a craft knife or scissors.
3. For the finger joints, cut V-shaped channels along the bend lines:
   1. Cut at a 45-degree angle in one direction along the line.
   2. Cut at a 45-degree angle in the opposite direction.
   3. Be careful not to cut all the way through the foam.
   4. Remove the small strip of foam left in the channel.

4. Use a heat gun to warm up the foam pieces, making them more pliable.
5. While the foam is warm, bend it into the desired claw shape.
6. Hold the shape until the foam cools and retains its new form.

Assembling the Claws

1. Use a belt punch or hole puncher to create holes where the claw pieces will connect. These holes will allow for finger movement.
2. Apply contact adhesive to the edges of the pieces you want to join.
3. Allow the glue to become tacky (this usually takes a few minutes).
4. Carefully align the edges and press them together firmly.
5. If the seams don't close perfectly, don't worry – we'll address this in the next step.
6. For the claw tips, use scissors to trim them into a neat point.
7. Heat the point with a heat gun and press the ends to smooth them out.

Finishing and Detailing

1. Seam filling: Use gesso or flexi filler to smooth out rough seams.
   1. Apply the filler along the seams.
   2. Smooth it out with water and your finger.
   3. Let it dry completely.
   4. Lightly sand with 600 grit sandpaper to remove any imperfections.

2. Priming: Apply a paint-on primer like Flex Bond or Hex Flex.
   1. Cover the entire surface of the foam.
   2. Let it dry completely.
   3. Apply a second layer for a smoother finish.

3. Optional spray primer: For an even smoother finish, use a spray primer like Rust-Oleum Filler Primer. Note that this is not flexible, so use it sparingly to avoid cracking.

4. Painting: Once the primer is dry, you can paint your claws.
   1. Use acrylic paints for a matte finish.
   2. Consider using nail polish for a glossy, marbled effect.

5. Detailing: Add any additional details or weathering effects to enhance the realism of your claws.

6. Sealing: Apply a clear sealant to protect your paint job and add shine if desired.

Attaching the Claws

1. Use paper brads, fasteners, or rivets to connect the claw pieces at the joint holes you created earlier.
2. Ensure that the connections allow for comfortable finger movement.
3. Test the fit and make any necessary adjustments.

Tips for Success

• Always work in a well-ventilated area, especially when using heat guns and adhesives.
• Test your paints and primers on scrap foam before applying them to your final pieces.
• Take your time with each step to ensure the best possible outcome.
• Don't be afraid to make multiple attempts – practice makes perfect!

Customization Ideas

• Experiment with different foam thicknesses for varied effects.
• Add texture to your claws using tools like a wood burner or texture rollers.
• Incorporate LED lights for glowing effects.
• Use different colors and finishes to match your character's aesthetic.

Maintenance and Care

• Store them in a cool, dry place away from direct sunlight.
• Avoid crushing or bending them when not in use.
• Touch up paint as needed before each use.
• Clean gently with a damp cloth if they get dirty.
