I love going to thrift stores. We have one that has samples of quilting fabrics with the name of company etc. there are usually 3-4 nice size pieces and I buy about 4-5 of each pattern series and I wind up with quite a bit of the same fabrics to put in a quilt.
They are only $1 each. I have picked up enough "Snow Buddies" to make a quilt. Quite nice.
