I not only buy them, but have also started cutting 5" squares from all fabrics I use in other projects. It is amazing how differnet liness enhance each other. I love using them in DP9, DP4, folded (prairie points) blocks, 10 minute blocks and 5 minute blocks. I often just combine them with some solids or semi-solids that bind the whole caboodle together. The are also great for folded hexagons and Rob Paul to pay Peter type blocks. I'd be lost without my charms.
