Introduction: DIY Halloween RGB LED Kitty Ears
needle and thread
Optional but recommended:
copper tape or wire
Step 1: Cut Out Paper Template
Define the height you want the ear to be - by holding a ruler up to you head (highly scientific approach) - and build a triangle similar to shown. You can use these shown measurements as a guidelines - but your proportions might be a little different.
Adjust the shape to have the curves following a more natural outline of the ear. Cut out the paper triangles..
Step 2: Cut Out Fosshape
Trace the template onto the Fosshape. Cut out 2 large shapes and 4 smaller shapes for the base of the ear (two bases per ear).
Step 3: Sew the Ear Parts Together
Sew one ear shape to one base
Step 4: Harden the Fosshape
Now shape and harden the ears using a steamer or heat gun. They will shrink about 1.5 times (left ear treated with heat and right one not yet shown for comparison), so take that into consideration when choosing the final product size.
Step 5: Hair Clip
Sew the second bottom to the ear and insert the hair clip. Heat shrink the bottom layer.
Step 6: LED
Insert the LED into the inside of the ear with legs poking out from the other side.
Step 7: Optional Step Involving Soldering
In order to assure good contact of the battery with LED legs by increasing the contact surface, you can use 2 pieces of copper tape (or stripped wire) and solder them to the LED legs:
- Pre-tin the copper tape or wire
- Solder them onto the LED legs
* The photo doesn't show it but the copper wire/tape needs to be soldered on once the LED is inserted through the ear as shown in previous step.
Step 8: Battery Pocket
Bend the LED legs so they make contact with the battery. Cut out of a little rectangular piece of Fosshape to serve as a pocket. Sew the pocket with the battery around it. Leave the pocket open at the bottom so it's easy to push the battery out when not in use.
Step 9: Test
Pop in the battery the right way - test test, it works!
Step 10: Heat Shrink
Heat shrink the battery holder tab with the battery in it using the steamer or heat gun.
Step 11: Rhinestones
Use hot glue to attach the flatback rhinestones to the inside of the ear
Step 12: Fur
Use some tufts of fake fur to disguise the bottom of the ear
Step 13: Finishing
Use some ball chain to finish the ear edges!
