I use them occasionally. It depends on how many fabrics that I need for the pattern. the thought of picking out 40 fabrics gives me a headach. Plus I could never find all the variety of fabrics that come in a pack. I am now working on a welcome Wallhanging that needs ony a charm pack. I got one for $9.5 with lots of coordinating colors. Since that is all I need it is cheaper then buying 1/4 yd of these fabrics.
