This is Marjorie Busby from bluefeatherquiltstudio.com, and I love, love, love the GO! QUBE. My first reaction was, “Why would I need this when I already have almost every die that AccuQuilt makes?” The answer was obvious before the package was hardly opened. With the QUBE, everything needed is at your fingertips. Cutting the exact number of pieces for each block is a breeze. It is like the BOB dies, except that there are an infinite number of blocks that can be made using this one set of dies. And best of all, the 4 x 4 patch blocks can be made in any size: I chose the 9" QUBE and love that I can make 4 x 4 patch blocks in that size. It opens up a whole new world of cutting for me. The more time I spend with it, the more I love it for both piecing and embroidery.
