Display Bins for Art Shows

I was wondering if anyone has suggestions on where I can get fairly low cost display bins to display smaller, non-framed images at art shows. These wouldn't need to be free standing. They'd be placed on a table. I've found some on the web, but they're all a little expensive. I don't want something really cheap looking, but don't want to pay much more than $20/bin.

Thanks.

Define "smaller" prints. I'm using free-standing fold-up art racks right now; found them at Guiry's. They carry two different brands; one comes in three sizes, and one of the sizes is good for putting on a table for 8x10s. I've seen people who make their own, too.

You could always build them using some 2X4s for about 5 bucks.

Grant, I had mine custom made and so they cost quite a bit. Tony L and Dave R have mentioned some clear plastic holders that they use, but I think they cost quite a bit more than $20 per bin. Sorry I can't be of help!

I found some decent white cardboard display bins at Expedx. Photographer's Edge offers similar items in the $5 to $10 range.

Thanks for the feedback. Les, these would be mostly 11x14 and 16x20 mats. I may now go with a free-standing metal print rack for the larger ones and the following wicker baskets for the smaller ones:

Still open to suggestions, though.
