Blisters on your fingers? Worried about permanent gouges worn into your hands from tying knots for your beaded teething rings? These Knot Grippers are going to rock your world and are the perfect tool for all your crafting needs! INSTRUCTIONS: After you have tied your main knot, simply tie another knot on each of your pieces of excess string. Then, slip these extra knots into the slots on each of the Knot Grippers. Give a good pull and your main knot will end up tighter and safer than ever- with no discomfort like before! Extra Tip: The closer you tie your knots on the string to the main knot, the easier it is to get a stronger pull! Knot Grippers come with two pieces. We are proud to source this completely unique tool from the original designers and know it will be an essential part of your crafting toolbox!
