My mom has seen a lot of my projects that incorporate LEDs into clothing and so for Christmas, she said she wanted light up slippers. She has peripheral neuropathy after undergoing chemo. It wakes her up at night and she wants to get up and walk around the house but doesn’t want to wake up my dad by turning on the light, so these are the perfect solution. I made these slippers from scratch, but you could definitely mod some slippers and skip most of the sewing.
