Using the Katrinkles Darning and Mending Loom Kit is easy. First, place the garment or sock with the hole over the darning loom. Then, use the heddle to create a base for mending. Attach the elastic tie to keep the fabric in place. Thread the tapestry needle with your chosen thread and start mending following the instructions provided. When you're done, remove the item from the loom. As for maintenance, keep the tools in a dry place. After each use, make sure to clean the darning loom and heddle gently. Avoid bending the tapestry needle and store it carefully to prevent it from getting dull.
