Ok so before I caught the bug, the quilting bug, I bought many different fabrics and I never kept track of what everything was or what it was made of! NOW....I need a piece of solid brown fabric, I went to the fabric shop today and walked out with everything I needed minus the brown fabric (I forgot it and it was what brought me to the shop in the first place!) I went through my box of scraps and found a brown fabric that will matches the fabric I am using in a quilt...BUT I don't know for sure that it is 100% cotton, I do NOT want to use it unless it is.
Is there a way to tell if something is blended fabric or 100% cotton??
