I am totally confused. I prewash because I puchased some Kona cotton which was orange and I purchased some navy blue Kona. The bleed on the orange in places. So I had to get that out and then wash the blue two times before it would not bleed. All of this is 100% cotton.
I do not know what to do about the jelly rolls. I am like the ladies above, I would not wash it either.
