I just finished a quilt throw with bamboo batting. It literally drove me crazy. I didn't wash it first so that might have been the cause, but it shed terribly while I was trying to do machine quilting (I had about 2 inches sticking out around the 4 sides). The dark colors in my quilt were covered with the bamboo hairs. I had to keep using the lint brush. It also would pop up through the needle holes. Once I washed my completed quilt - I had little balls of the batting all over the quilt & had to use the lint brush. If I would have washed it first, my washer could have been covered with that lint! urgggggg!
