Well, I liked the background, except for the black line at the bottom LOL And it looks like patterned/ribbed glass to me, on my computer.
On a fluke, I've been taking some of our pictures on two pieces of 'patterned' vellum-- guess its supposed to be like marble or something-- a white on white. It was all I had at one show as I was cutting some paper items and just used it. I've used felt, velvet and for a while, a scrap of cream burlap was my favorite background choice.
But I truly thought it was a cool piece of narrow ribbed glass-- which might really make anice backdrop!!!
To keep down some of the glare, try holding up a piece of white paper to shadow it just a bit, kind of like a photographers' white umbrella. Now, if only I took my own advice........ lol
