Anyone ever tried a Scrapbooking Round Robin?

I'm pretty new to this site and I've noticed that the members do round robins with seeds and other items. Has a round robin for scrapbooking ever been tried? I know that I sometimes buy embellishments and then realize that it wasn't really what I wanted for a particular page and so it sits until I decide to use it. It'd be cool to trade them off with another member.
I've never done a round robin yet, but I think it would be alot of fun to do one for maybe just stickers, brads and other small embellishments.

Is there a member here who's participated in the round robins who would give her/his opinion on doing this? I'd love to be in one :)
