I took a needlepoint class on an 18-mesh canvas the week before my CraftOptics glasses arrived. The instructor demonstrated several of the more complicated stitches, and we worked a bit on our canvas using the stitches so we would have something to look at when we got home after class. When I looked at the canvas using my new CraftOptics glasses, I was horrified at all the stitches I had done incorrectly just because I couldn’t see. I was even wearing a fairly new pair of glasses with a new prescription. I had to rip out what I had done in class and redo it. Now I never do any needlepoint without my CraftOptics glasses. As someone else told me, they are a game changer.
