Even if this Lil gadget is expensive, it makes turning these tubes super fast and easy. Everything stays in line, no hand cramping, no struggles. I used a glue stick to fasten the next 21/2" strip on and when batting was getting twisted, I cut the batting in a V shape, untwisted and glue stuck it back on the strip where I cut the V. I made 1 rug without this gadget and a bag with this gadget. It made the bag making super easy.
