These grime guards are for QSnap used for hand embroidery (including cross stitching). I have a friend who has just started CCS and has purchased some QSnaps. Her first project ended up getting pretty grimy from her hands, so I've made her some grime guards as a Christmas gift. They were quite easy to make. I used an online tutorial for the measurements. One is for an 8" size and the other is for an 8"x11" configuration.
