Help-Jellyroll patterns?

Wow, two posts in one day. My two jellyroll packs came from Hancocks last week, black/white and retro. They're calling to me, but I don't know what to do with them. Does anyone have suggestions?

Another small project done

I took a class in May on Seminole Piecing. We used the technique in a tablerunner. I decided to do it for a friend. 

 Her birthday was in June and she told me that there was no hurry. I replied that if I didn't work on it now, that it might go on the pile of UFO's and disappear into the storeage room. Heaven help it if that happened. She quickly agreed that it would be a good idea for me to keep working on it. I gave it to her yesterday and she was really pleased.
