Craft Question: I need to find a hoop, circle, not embroidery hoop (Details follow)

I need to find a hoop, that I can put some large wooden beads on. I don’t care if it is metal or wood or anything as long as it is in the shape of a wreath (a circle). An embroidery hoop will not work because I need to string beads on it, and those hoops are flat and too thick . I was hoping for a metal hoop of some kind.

Is there a ready-made circle (with an opening of course) that you can think of that would fit this bill? For example, I saw a belt hanger in a shop and it is a metal circle with a hanger attached to it, but it was too small. This should be a larger diameter in order to make it wreath size. Maybe 8–10-12 inches?

So, any ideas for ready-made circles, hoops that I could use as a base for a wreath? (Remember I have to string some large wooden beads on it…so it cannot be an embroidery hoop.) And no, I don’t think I can get a perfect circle by bending wire, etc. A thick wire or ready-made metal hoop would be perfect…but I haven’t been able to find one.

Thank you so much!
