I love my GO! I have 7 dies so far and will be adding at least 4 more as soon as I can. I use the 2 1/2 strips to cut binding and I just recently used it to cut 6 1/2 triangles to make my cousins wedding anniversary present and it took me about an hour to cut 200 of them from 4 different fabrics and they were all perfect.
If you cut the fabric to be a smige bigger than the item you are cutting its not that much waste and I am braiding mine as I go, not sure what I will use my giant braid for but something will come of it.
This is the quilt for my cousin
