Wedge used in the groove of Universal S Loom to make a smaller complete circle for hats, slippers, and more. Comes with any 1/2", 7/16" Universal S Loom. Can be ordered separately.
Giving a 5 star rating because I love these looms! I have the 7/16 afghan loom, and think this hat loom will be great. I like the Cindwood looms better than the KBs.
