I actually find the colors to be too subtle. I would be willing to bet that people will mention the wrinkles and folds in the fabric. I like it, they add a dimension to the shot. If they weren't there, you'd have a shot of a placemat.
This meets the challenge as far as presenting a pattern, but lacks a bit as far as a photograph. It's kind of bland - there's really not much to see other than what appears to be a plaid sheet or pillowcase. If you're interested, I'd be happy to suggest some things to try to reshoot this to make it a bit less plain - feel free to PM me.
