I usually use Hobbs 80/20 and soak it before using, it's lightweight and holds up through washings. Some like the puckering when quilts are washed as it looks 'old fashioned' but I like the flatter modern look. Of course there are times when other batting is chosen, I do like Quilter's Dream and used it in quilt DIL asked to be heavier than the quilts I made for grandkids. Grandkids first quilts always had a good poly batting as I knew the quilts would be washed many, many times.
