Starting out, I used to purchase random "just can't live without it" fabs...and "fill in the gaps" when "the right pattern" appeared. But, as time goes on...am purchasing in coordinated groupings. There are so many groups of fabrics to chose from these days. I just zero in on favs...and whatever seems to work for my pattern...several selections from "the group," and add other accents as needed. (Of course, there are always those strays a gal has to round up!)
