Perfect for all our young weavers who want to do more weaving. Designed for Size A, but can be used on Size B too. Pure Virgin Wool for beautiful projects of the highest quality. Easy Weaver A Refill Kits include:A wool warp 6-1/2" wide x 2-1/2 yards long, enough extra yarn to weave the entire piece and instructions. We made re-threading your Easy Weaver with a new project a breeze with our Refill Project Kits. Of course, the yarns are 100% pure wool made in our own Harrisville Spinning Mill. Once we've measured out just the right amount, in just the right order, to thread onto your Easy Weaver, the warp (2 -1/2 or 3-1/2 yard set of yarns to be wound onto the loom) is chained to make threading easy and tangle free.
