It will all depend on how much you do those kinds of quilts?
I haven't found any quilt pattern I can't use the Go dies. Double Wedding Ring, Winding Ways, Snail Trail, Orange Peel, Log Cabin, Baskets, Churn Dash, Kite, Ohio Star, Blooming Nine Patch, Drunkard's Path, Rag quilt, strip dies in many different sizes including hst, triangle, diamond, chisel, rectangle, wedge, square, and many applique shapes. I like the BOB (block on board) dies the best. Every piece of the block is cut at one time. Layer six fabrics and have six blocks cut in five seconds. Accuquilt has a 50% off die sale all July. I bought all the ones that were on sale that I didn't have with free shipping. I have over 60 dies.
