Thanks guys for the feedback. My work lights are 500W each. I went to a Michael's craft store & bought that white card stock that is hanging down.. you know, the kind that is 1/4" thick with foam in the middle.
If you want to spend a little more, those work lights come with stands (Lowe's, Home Depot). I used some crappy roller stand tripods from HF. I am a cheapskate, so I got this done for $30 or so, not counting the fabrics I bought for photo backgrounds.
