hey i did the same thing at my house. Go to www.studiodepot.com ... they have lots of blue and green screen paints you can buy. i personally suggest the Rosco line of products. Then buy some pre- primed plywood, paint the wood and ur set. just in case u didn't know, if u do this and it doesn't work out on the computer as well as you'd like, it isn't the paint's fault, it's the lighting.. the blue/green screen has to be evenly lit. good luck.(posted 7888 days ago)
