I use my Go for 99% of all my quilts. I have had it since it first came available. I bought most of the dies that were available for it then. Over the years I have added dies as I wanted them. I buy mats to fit the die. For one shape on a die with multiple shapes I use the smallest die to cover over the one shape I want to cut. I have all the cube sizes but they were gifts. I buy most of my dies and mats from Amazon through Accuquilt. The mail packaging is better and still the same warranty. I get free two day shipping with Prime. Excellent cost free returns if a die skips or is defective.
