Thanks for the review. I would expect cotton and bamboo to shrink, and I like the crinkly look, so that would be fine. I also like the non-crinkly look, guess I'm just not too particular about that aspect of quilting. I am surprised that it would shrink after pre-washing though.
What I wanted to say was that hanging a quilt to dry isn't usually recommended. When the quilt is wet, it is very heavy (as you know), and the hanging weight can easily cause the quilting threads to break. If you have a place to lay it out on the floor, or on a sheet on the lawn, it can dry that way. I usually put mine in the dryer on low heat, and take them out when they're almost dry, then finish drying stretched out on the carpet. Or sometimes I just let them finish drying in the dryer, always using low heat.
