With the bundle, the 5 1/2"(5" fin), the 4"(3 1/2")fin), and the 3" (2 1/2" fin) square were included, along with 5" quarter square triangle, 2 1/2" fin HST, 3 3/16 x 4 1/4" parallelogram, 5" finish HST, and 3" x 5 1/2" rectangle. I feel I have a good start.
I use 2 1/2" strips/squares a lot, but have read of people not liking to cut their strips with the die. Those of you who do, convince me why it's better than ruler/rotary cutter.
