This 7/16" Wedge is for oval panel loom and X looms. You can order extra wedges incase you loose one or want to use more than came with your loom for a current project.
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.
