I love my Go and use it mostly to cut 6 1/2" & 8" blocks as well as 2 1/2 strips. I have several other dies and I am sure I will use them as I get more into cutting fabric for my "bucket list" of quilts I want to make for my grandchildren, GGC, nieces and nephews.
Shop for prices. I just happened to get mine at a garage sale and it was new. I have gotten all my dies on sale at various places.
Also, always starch (I use Best Press.) and press before cutting with the Go. It really helps the shapes to be accurate, especially when cutting strips.
