lynnie - I don't know how big your turkey is but did you look at any antique stores/flea markets? I see the prettiest small saucers all the time at those type of shops. It wouldn't be a platter shape but you may still find something. I wouldn't mind getting a 'naked' turkey. LOL.
Can you make one with aluminum foil or paint and cardboard? I know you guys are envisioning some cheap-o looking thing, but in my head it could work. Or at least the voices tell me it would...
mdall - can't wait to see what you do with the rings. I can think of one thing, but don't know if I am guessing correctly either.
I have mine finished and they will go postal on Monday. And for whomever asked to see pictures - I have a Swap photo album linked in my profile. I have posted pictures of sent and received pin cushions there if you are interested.
