One of the dies I have is for 2.5" strips. One thing I do not like is alot of waste so I put my fabric on the die and was careful not to have too much going over the blades. The fabric was a full WOF piece folded over so I cut through 4 layers. The die cuts three 2.5" strips at a time.
In this photo I have the strips stacked but wanted to show you the leftover. This is about how much I would have cut off to straighten fabric with my rotary cutter. I could see that the GO! will certainly speed strip cutting.
