I also have the Go & am now using it to cut 2 1/2 inch squares. One thing that I've found that really makes a difference in the accuracy of cutting absolutely square is to place the fabric correctly on the die. It must be placed with the least stretch (lof) feeding into the roller. Placing it with the width of fabric feeding into the roller makes it stretch some & therefore the squares aren't really square. Just a tip for those who might be getting this die. I hope this is clear???
It sure does make cutting a lot of squares easier & quicker.
