I LIKE the effect of the bleeding....especially if it's dispersed throughout your blocks. It provides some additional interest and makes the blocks look VERY "vintage". Once the blocks are made into the quilt, I personally would hope that there would be MORE bleeding because it looks like the lighter fabrics were over-dyed or hand-dyed and it softens the overall effect. Embrace the "funkiness"!
When life sends you lemons, make lemonade.......
