Quilted Twins has a lot of free quilt patterns and I just finished one called Trail Mix though I don't think that pattern is still on their website. Then there is always Bonnie Hunter's site as she's all about scraps and how to deal with them.
I also have a top called Rick Rack but don't know where I found that pattern but used a bunch of my scraps for that one also.
Good luck on using your scraps.
