Step 6Attach Backing to Vinyl Strip
Preparation
I chose to hold the wiring, resistors, and LEDs in place with duct tape. I don't know if this will do any good, but I'm hoping it will help keep everything in place and minimize the chances the circuit will break in use. I also used a small piece to hold the top ends of the red and black wires in place.
Prepare the fabric strip
Cut two strips of fabric - these will serve as the base for the Velcro. Since the duct tape was 2 inches wide, I cut the fabric 2 3/4 inches wide, leaving room for a 1/4 inch hem on each side and room for the fabric to have 1/8 inch beyond the duct tape. This is to protect your sewing machine - you don't want the needle to pass through the adhesive from the tape. The fabric should cover the wiring plus 1/2 inch at the bottom and 1/2 inch at the top.
Turn over each side of the fabric 1/4 inch and stitch in place to create the hems. Check to make sure it will cover the entire circuit plus the 1/2 inch at top and bottom.
Sew on the Velcro
Stitch the prickly half of the Velcro to the right side of the fabric. This allows the soft side to go on the pants, which I think is nicer. I had 3/4 inch Velcro handy for the first leg and then bought some 2 inch Velcro for the second leg, so I have pictures of both. Both sizes work, just be sure you've got Velcro at the outer edges of the fabric strip for greater strength.
Sew the Velcro strip onto the vinyl strip
Stitch the Velcro strip to the back of the vinyl strip. Be careful to center it over the wiring and make sure the edges are clear of the duct tape. Note that the vinyl will be wider and longer than the Velcro strip. Stitch the sides first and then the bottom. Next, remove the small piece of duct tape holding the top ends of the red and black wires in place. Carefully hold them at the center of the strip while sewing the left top of the Velcro strip to the vinyl. Repeat for the right top.
The LEDs strips are complete!
