I have a lot of fabric that I have collected thru the years and I know some of it isn't 100% cotton. Isn't there a test you can do to check to see if it is all cotton?
And if you make a quilt and some of the squares aren't all cotton, what will happen? Why is 100% cotton prefered fabric? Can you make a quilt out of poly-cotton fabric if you pre-wash the fabric?
Thanks in advance. I appreciate all your helpful answers. This has been the best group of people that give great advice.
