I just purchased a photographic backdrop stand to use when taking pictures of my big quilts. Until now I've had to lay them out on the floor and then stand on a coffee table, and the pictures were never very good because of the angle. The only alternative (for me) was to hang them over the side of the balcony (indoors), but the light was bad, the space wasn't wide enough, and the stairs showed in the pictures.
I found this stand on amazon.com. It will expand to 12' wide and 10' high. It comes in a good quality case with a carrying strap. It adjusts easily and has tripods on the uprights. I did have some trouble setting it up with a big quilt, on the grass, on a somewhat windy day (attached picture - DH is holding one pole steady) - but on a flat surface, without the wind, it will work great.
(Yes, you've already seen this quilt - but I'll bet you've never seen such a good picture of it!)
