I have a Go Baby and love it for cutting triangles and other shapes that are not rectangles or squares. I have trouble cutting accurate sizes with the square and rectangle dies, so I gave up on those. The dies would cut a piece of paper accurately then when I used fabric it would distort the sizes--enough distortion that I couldn't piece the pieces accurately. I was using different weights of fabric in my quilts--all 100% cotton but different weights and thread sizes. As I mostly do scrappy quilts with fabric a friend gives me, I found that with the assortment of fabrics that I use I couldn't cut the fabric accurately.
