My Christmas present last year was an AccuquiltGo cutter which I am using constantly. While it was an expensive and the additional blades are not cheap either, if one plays with junk fabric?? one can make all kinds of shapes. My most beneficial is the 2-1/2 inch strip cutter which cuts three strips (from salage to salvage). Of course I double up two pieces of fabric at the same time and come up with 12 accurate strips. Waste I intentionally make at 1 inch and throw into scrap quilts. If I do not want strips, then I cross the strips vertically and cut 2-1/2 again, making perfect squares. (Hearsay is that those who have the BabyGo cutter have not been very pleased.)
It works great on coordinating fabrics. I go straight from cutter to the machine and it is done.
Of course, the best advantage is the fact that I have arthritis in my hands and this alleviates all that. Good luck in finding what you want.
