they have tons of different shapes to use for the same style of sewing as the grandma's flower garden...i did tumbling blocks as a traverer that was wonderful and there are lots of others. i love having a traverler ready for any time i get to ride instead of drive or in dr. offices, where ever there is a wait!
they also have free design sheets you can print off and color with colored pencils, and use to design your project ;)
