Have you ever dyed threads? I've dyed some clothes in the washing machine before and once dyed a bed sheet for a fancy dress costume where my OH was going to a party in traditional Arabian costume, but never threads for embroidery.
After a delay of a week, due to the snow, we managed to get some dying done in my creative embroidery class and it was such fun! I had a bit of a production line going, as you can see, and managed to dye quite a lot of different threads and some pieces of calico.
Now I need to creatively merge these colourful bits into a project.....MMmmm?
