I'm doing my own sort of Project Spectrum this year, inspired by the Online Guild of Weavers, Spinners and Dyers. I'm starting with red, so here's a mosaic to get started:
Clicky clicky to see it properly on Flickr.
I've spun up two batts as a final piece, I'm just waiting for the yarn to dry and I'll take pictures.
I'll probably discuss this project a bit more sometime soon, right now I'm too cross-eyed and tired!
