Step 6Hiding the rig

I decided to soften the transition between my one inch table and the rest of the blanket with a frame made from two layers of 1/2" green foam. I also notched out of the foam at resting place for the battery holder and the switch. I also just tucked the 64th LED into the side of the foam frame, you never see it in the end. This allowed me to set these off a bit from the table, as I don't want spills to head into the electrics. The PVC layer helps this and if you want to, you can silicone the seams between the vinyl and PVC before topstiching.
Spray the back of the foam frame and center in on the grey vinyl layer. Let this set up and check to see it is secure. If not stitch through it to the backing, my machine will do this but if yours can't just tack by hand.
