advice on this background

Personally, I don't think it would go well with Angels, you don't have to be Martha Stewart to DIY a nice background.
 
I took a frame work of one inch pipe and acyrilic base's one for the bottom the other a shelf over hang and used slate tiles and wood and built my own for about $50.00.

Do you have any pictures of this, or a link to a DYI?

Thanks
