solar colour changing thread indoors

solar colour changing thread outdoors

I was looking into ways of harnessing solar energy other than using actual solar panels and happened to come across this – it’s embroidery thread that changes colour in the sun.  It would be great to try this out using the embroidery machine!   I think I’m going to order some, if anyone else is interested, maybe we can order some together…
