I don't know if this will help, but the first nine quilts I made were made out of muslin, except for the sashing, border, backing and binding. I had embroidered on the muslin. I used Warm and Natural batting. I throw them in the washer, hang them on the line and they are good to go! I will use a little Shout on a spot and it comes out! My next quilt is white on ecru with triangles of dark and light fabric (Floating Stars Scrappy Quilt) To be honest, I haven't had any problems with the washing or anything. Good luck to you. Edie
