Jelly Roll Twist, a free-I think-pattern from Fat Quarter Shop uses a jelly roll and a charm pack to make a throw. Extra yardage could be used to make a border and/or binding. It suggests using a solid color charm pack but I've seen it done using coordinating jelly roll and charm pack. Quick and easy pattern that looks great. A number of people in my guild made this throw.

What about MSQC's Summer in the Park? There are two ... one with Natalie (Jenny's daughter and the first video and the one I'm referring to).....the second one is with Jenny and called Summer in the Park revamped.

I also bundle a pattern with my precuts. Or will put a note in with the pattern what fabric/precuts I want to use with it.
