I like the strip dies. I also like the triangles. I can't imagine curved patterns without the use of a die. I'm not that good with rotary cutting them and they fit together so well if they are die cut. I have made several using the Winding Ways BOB. I have also made several quilts with the chisel set (chisel & matching triangle). Having said that, everyone is different. Are you attracted to specific patterns or do you find yourself cutting the same shape over & over those are the dies you should get first.
