I dye a lot of textiles, mostly silk scarves and tee shirts, but some friends asked for some bright custom dyes for a 5" charm swap we were doing. I dyed up a bunch of bright cotton and my 19 year old niece came through as I was cutting it up and fell in love. I used the extra and made her this quilt for her first real apartment (she's in college.) There's no particular pattern, I just cut 6 1/2" blocks and sashed them. The black really made things pop.
I used fiber-reactive dyes and kona cotton.
