I have just started to use my new Stripology XL and so far, it is fabulous! I used to be scared of cutting fabric for a quilt and really love to do jelly roll types of quilts, but this product makes cutting a breeze. It does not shift easily on the fabric, so stays put while I cut multiple strips through several layers of fabric. I also learned how to use it to square a half-triangle block. Can't say enough about this really important tool that makes the job easier, more accurate and saves a significant amount of time. Love it!
