Hi,
You might try HGTV.com and go into the Carol Duvall show. I would try the ones in previous years and you might find a pattern. I will try to think of some other sites but this one may lead you to others too. There are a lot of people who sew. Unfortunately I do not sew a stitch and admire anyone who does.
Hope this helps.
Just thought could you use small plates and make your own pattern. I can see each segment a different color with two antennas.
Just a thought.
