Its motorized and I guess the muslin is too light(though, it is a thick heavy handpainted muslin vs ones that feel like sheets) and they wind up wrong. The canvases do fine. I am about to sell off some backdrops again and go with large thunder gray paper, white paper, my favorite tan muslin(which gives me fits) and the one cream canvas.

I just bought three flex out backgrounds, that will be incredible for traveling. Next purchase is a gray style roll out floor to use with them. I like my life to be easy. Easy is very very good.
