COLORWORK!!! When I do colorwork, I put my MC on one side, snap it in place and then I put my CC in the other side, snap it in place and voila! No tangles, no balls rolling across the room and I can change bags in a second by just moving my Oh Snap to the bag of the moment. This product is a GODSEND for doing colorwork and the best $19 I EVER spent!!
I ordered both the large and small sets, and am very pleased with them. I'm using a large one and the smallest right now. The snaps feel very strong, I love the red color. One small snag: fine knitting needles do poke through the mesh. I have to find my point protectors. The smallest bag is great for holding tools.
