I just learned about the 1600 jelly roll race, so check it out my favorite jelly roll patterns come from cozy quilt check out their site strip club patterns tons to choose from. Severalmof theirs also use a focus or background piece too.
I seem to reference them a lot.....No I am not affiliated just a huge fan of their stuff.
Another pattern I really like and have used several times is road to Bali by legacy it's super easy.
