ok I finally did it. I bought 48 ft of clouds from BackDrop wharehouse today. 36" high by 12' long each. I need aprox 45 ft of skyboards. I have been looking at these for over a year. Looks like they might do the trick. Now to build the skyboard....
I hope you can post some pictures, a backdrop makes a world of difference. Mine is simple blue poster board but it is a vast improvement over blank wall or whatever.
