I saw images of rope light rugs and baskets on Pinterest, but no patterns attached to the photos.
I acquired a couple of cheap LED rope lights (approx 10m in length) and some light 't-shirt' yarn. Hopefully I'll be able to recreate the ones I've seen on Pinterest!
I made two baskets, one using 'warm white' LEDs and the other using 'cool white' LEDs.
It's very important you use an LED rope light, as it needs to not produce any heat!
