I'm making a quilt for a new baby and was anxious to get it done, but when I went looking for batting, couldn't find the Warm and White, which I usually use. But I did find a piece of polyester which was just the right size. Well, I used that and have the quilt about 1/4 quilted when I decided it might be too heavy and not soft enough. I live about 50 miles from a Hobby Lobby (my Hancock's is always out of cotton batting) I looked at batting to try to identify it and I think it's something called Therma Lam if I remember right. My thought was that was probably best for wall hangings and placemats. Question is, should I take it all out and replace it with cotton batting? It will certainly be a warm quilt, which is okay, but do you think washing will soften it up? Thanks in advance for your comments.
