A handy tutorial explaining how to put together the RGB LED Horns. Make your own, or get a kit with everything included (except for the paint).

Supplies:
Fosshape 300
2 x slow scroll RGB LED
2 x coin cell batteries
conductive thread
2 x coin cell battery holder - sewable
2 x pieces of velcro (hook side)

dimensional fabric paint (like this) - not included in the kit

Tools:
scissors
needle
heat gun
needlenose pliers
clear nail polish - optional

Step 1. Patternimg_0890Cut out your own pattern - a simple triangle and a circle for the base.

Step 2. Shape the hornimg_0898Sew the triangle along the long edge. Shrink and form it over the heat gun - make sure to watch the fabric, when heated too much it will melt and form holes. Instead of trying to form the hot Fosshape with your hands, the best way to harden the shape is to hold it above the heat gun making sure to heat it evenly and let it shrink. Shrink the bases too while keeping them flat, but don't sew them on yet.

Step 3. LEDs preparationimg_0908With needlenose pliers curl up the LED legs and bend them 90 degrees so that the loops sit flat when the LED is facing up.

Step 4. Battery holder

img_0907img_0911Grab the battery holder, a coin cell and the base and attach the LED using conductive thread. Make sure the polarity of LED and battery are correct. If everything is wired right the LED will light up.

Step 5. Sew the baseimg_0965Sew the base to the horn like shown and add a little tab of Fosshape and Velcro to the opposite side in order to keep it in place. Paint some clear nail polish on the bottom of the horns to isolate the conductive thread from touching the metal of the hair clip. Alternatively, you can fluff up the small scraps of Fosshape and fuse them over the stitches to protect the conductive thread.

Step 6. Paintimg_0966Embellish the horns with a pattern of your choice using the Tulip paint. It will take about 4 hours to dry. The Fosshape disperses the light quite nicely.

Step 7. Hair clipimg_1033Hot glue the hair clips to the bottom of each horn. Alternatively, you can sew the finished horns to hair clips or a head band.img_0968web
