I finished a quilt a few months ago that I made mostly with strips I got at a garage sale. I didn't want to pre-wash strips, but kind of held my breath when the time came to put the quilt through the wash. I used the color catchers and had no problem, even though it had several batiks and lots of dark purple and teal interspersed with white squares. I don't have a clue how color catchers can be so effective, but they turned pretty dark gray in that load while the white fabric stayed white. While I think you can probably trust the store that is selling that fabric, pre-washing the bigger pieces with color catchers would surely help ease your mind. After all, if you had a problem later, they would earn a bad name, but you'd be the one stuck with a disappointment after many hours of work.
