@LianaBrooks I've quilted for years but not done much jelly roll. Guessing you're just doing the top, then embroidery, then adding batting and backing? I did a quick image search for rainbow jelly roll race and there were quite a few. That may give you a place to start.

@PurpleDragon Yes, I'm doing a very simple version of this. I want a simple back because I'm hand embroidering on a large dragonfly.
