Jenny Doan from the Missouri Star Quilt Co. has many tutorials on using precuts with her patterns. I would start there.
Also, whenever I see a pattern I like, I file it under subjects like, "2 color quilts", "Jelly Roll quilts", "Layer Cake quilts", etc. That way, when I need a pattern for fabric I've already bought, I know where to go to find a coordinating pattern. It's like working in reverse LOL.
