I have the Martelli ergonomic rotary cutter and love it....so when Martelli had their 1/2 price sale a week or two ago, I ordered two more...arriving today! That's a great time to purchase! I have an Accuquilt Go but never use it, so thinking about selling it. I mostly use my JT Shape Cut Ruler. I'm really interested in the Stripology Ruler, so if anyone can tell me the upside/difference in it and the Shape Cut Ruler, I would appreciate it!
