Someone already mentioned it - Quilters Dream says only 1% shrinkage. I did like how it washed up. I was amazed when looking at how much shrinkage some batts have - esp bamboo batting!!! My friend used that on a quilt and she said her queen size quilt shrunk 6 inches!!! YIKES!!!
Someone correct me, but when using cotton, it'll shrink and the quilt will still have that crinkled look (which i absolutely love!!!) But, is it possible to make a quilt that after it is washed, is still smoother/not crinkled like a quilt is when we first finish it.
