A friend told me about these cutters so I investigated and now I have had mine (GO) for about six months and I really think it was a good investment. I initially purchased it because of the ease of cutting "curved" pieces like winding ways, robbing peter.....applecore and yes this little cutter does really do a great job of those patterns...even cuts out the little triangles to match the pieces.......I have in the interim purchased a lot more dies thru internet sources, triangles, squares.....rag square is a hoot! and now am working with 1 1/2"strips and does a great job of eliminating many scraps...the secret I have found is following the cutting lines with a silver marker and making measurement notes right on the sponge....on and with the strip cutters you can do diamonds and squares by simply repositioning. But like everything else offered, we decide for ourselves what works best in our little world, in purchasing the cutter I have found something that I really feel makes cutting a lot easier and "fun" for me....enough said...going to go cut and sew now.
