What I use is called "FOUNDATION". A Expert Quilter told me this herself - a good friend of mine. This stuff you can write on and it is very thin and I mean very thin and it does not add any weight to your quilt whatsoever. I love this stuff. You can also mark on it as well too. You have to ask for this stuff at JoAnn Fabrics. I do not know how it comes whether it comes in sheets or by the yard or anything like that. This is almost like Mohair...that is how thin it is and it is so easy to sew right through this stuff either by machine or by hand. I love this method.
Thanks for all of your comments.
