Yesterday I went and picked up boxes and boxes and more boxes of fabric from this very nice lady (I had to take them all)..She told me that she is a hoarder and is in the process of trying to get rid of things..She has a professional working with her in the house getting things organized .Some of the fabrics are very old and some not so old, some has stains that I am not sure that can be removed..Quite alot are knit type of fabrics..There is so many types of fabric that I am actually over whelmed..My question is what types of fabrics can actually be used in quilts? Some of these fabrics are beautiful..I know there is silk, knit, poly, cotton, cotton blends, denim, sear sucker..ect...
