Garage sale stuff

Picked these up for $2 and $1.50 at a garage sale.

Item #1: This was labeled "embroidery frame," and was a totally disassembled taped-together bundle, so I thought it was a square tabletop frame. It looks like it is not a frame at all, but a stand. I can't figure out how it is supposed to work.



It looks too high to be a tabletop stand and too short to be a floor stand, so. . . ?

I figured that the pieces with rubber feet are the base, but that's about as far as I got!

Any ideas?
