My thought was similar to wolfkitty's. If you or DH could make a stand like a clothes tree, like a straight free standing square, tall board, and put hooks up and down the board on all four sides. I'm sure this doesn't make much sense but picture an artificial Christmas tree before you put the branches on. You could hang bags on all sides.

what about a board with those 3d white hooks, you know the kind you pull the tab and it then can come off? My friend uses them for everything.

Hinged ped board and use "S" hooks.

take a screen frame and nail the lattice boards to the back. paint, decorate, and hang!!!!

I use the clothes racks, BUT I zip tie peg board to them...front and back so it can be seen both sides..IF you have the room to do that..if not one side is plenty!
Paint the peg board a nice neutral color, but not too light..you can find the small hooks for the peg board at Lowe's usually. YOu can also get Shelf brackets for the peg board and put a small shelf on the top and bottom for stability! and for standing bags!

Good luck!

I recently purchased two wire grid walls for my booth , they made a HUGE differnence ... as you can get more display at eye level and just above . People will look up a little , but anything below 2 1/2 feet is like no- mans land.
They are not too expensive and are quite flexible as to the way you can use them. They do come in various sizes.
I did make a modification to the the hardware that was sent for the feet. I purchased wing nuts to replace the tiny nut they provide. The wing nuts make it much easier for a faster take down. Just wish I had gotten them sooner.
Oh one more tip .. for the tote bags .. I use balloons for a filler in the bag.

If you have one, a wooden drying rack will work for a hanging display. I'm thinking of the ones that scissor in and out and lock in place. A folding screen can also be used if you find one that you can tack nails or hooks into. Any two pieces of wood will work with hinges so that it folds flat to travel and when open it forms a triangle shape. I've seen two long louvered/shutter panels hinged toether. Several louvers were remove across from each other to run boards through to make shelves and to keep the panels in the V shape to stand up.

Why couldn't you use the canopy inside?? They do at our mall.

How about hinged peg board stands?

Please post a photo of your booth! I would love to see how you decided to display your totes.
