Congratulations!
I just purchased a Go Cutter and I also purchased the 2-1/2" strip cutter and mat. Great for tube quilts and borders or for 2-1/2" squares.
The flower cutter would be great for appliques but when you buy the Go cutter, you get a square and a triangle cutter too. So I opted for the stip cutter. Next purchase I will get the 1-1/2 strip cutter.
