I mixed a home brew "suntan lotion" with instant tea one summer. It was the only summer I ever got a tan. LOL
The tea dyed my skin just enough to look like a natural tan. It didn't protect against sunburns.
You might use some of the reproduction prints in that dresdan plate you are working on. I like the antique green. I think Keepsake Quilting has some of the reproduction prints and some solids. Post a photo when you get it finished.
