I feel like a Paslov dog. I am salivating. Awesome!
As far as the background, well, all I see is good food. lol.
However, instead of searching for that perfect tablecloth, you might try fabric stores in search of that perfect color you want or need. You could pick up several pieces to experiment with.
Or home improvement stores for wallpaper or laminate for the wood look. I don't know if those would work in photography though.
I am glad that you found something good in those images.
You know, we actually did go on a hunt the morning those images were taken.
We went to Target, Bed & Bath, and Pier 1, looking for backgrounds and bowls, and the placemats that we bought did not work out.
They caused the images to look distorted, or my spouse felt that they just didn't "go with" the food we had.
I will try fabric stores, and even a place that sells home furnishings at some point.
I have seen decent images on the Internet that had bare wood surfaces, and I have seen those in The Home Depot.
Maybe I get lucky and find some backgound at some antique or salvage place.
I liked the items that I viewed on-line at Ink and Elm as that they reportedly featured a satin or matte finish, which would help cut down on highlights or reflections.
Their products look intriguing.
BTW, someday I will try those Walking Tacos made with Frito's.
After your post, I read a lot about them.
I would love to produce some decent "Danger Dog" images someday as well.
