I was in a quilt shop once and noticed a quilt with the pictures done on it. When touching the picture fabric I noticed it was real soft as the natural washed fabric would be. I was hoping the BJS would leave the material this way. I do not like the feel of the pretreated sheets. They sometimes with wear seem to make the picture kind of looked cracked or something, maybe wrinkly. I can't explain what I am trying to say but you probably know what I am talking about. Maybe it was a different kind of material than muslin I don't know. As you can tell I am a beginner quilter. I love it, and am not doing any work outside of home as of now, but still do not seem to make time for it. I am glad to have found this sight and to be able to ask questions from people whom know what they are doing.
