Hm, I just had a look myself and I really doubt that buying a pre-made one is the right choice for you. All you need would be some spring steel (or lighter materials like plastic etc.) and good strong ribbons (and maybe some rivets, but that's too much work, if you ask me, you'd have to punch holes into the steel first). You could even cut strips from the striped bedcloth which you used to make that lovely skirt.
