I got a steal on this seam binding but I don't need this many yards of black. I bleached it for about 20 minutes and it came out this color. The little strip above the roll was in a higher concentration of bleach and it got lighter. I decided to put less bleach but leave it in longer. I was afraid the bleach might put a hole in it but so far so good. I just need to dye it whatever color I want now. I'll post it when I do.
