Ideas for school sewing project ?

In need some ideas for a sewing project at school. The project has to be used inside as a furnishing like a cushion, pillow, quilt somthing like that. I have about 21 hours at school to make it and a little bit of time at home, but 80% has to be done in cl. I was thinking of doing a quillow (quilt that folds into a pillow) but i was wondering if anyone has some good ideas or websites? thanks :)
