When I decided to take up quilting I walked into the church thrift shop up the road and asked if they ever got any quilting fabric scraps.
She walked me into the back room and gave me at no cost over 10 garbage bags full of scraps! Some 2-3 yards some fat quarter size. Since then I swear that all those fabrics have multiplied!
Even after weeding out the polyesters somehow I still had those 10 bags crammed full! I am finally getting them all organized!
