There are lots of paper pieced mini patterns out there. I just finished a 6 inch square feathered star in tiny Halloween fabrics and a black on black. I am not sure I will make it much bigger, just add a border.
I just drew out a pattern for a paper pieced girl and four of them would make a cute small quilt. I can embellish the skirt.
Log cabin blocks are also an easy thing to make and mostly use scrap. I made a whole wallhanging with 4 inch log cabin blocks out of scraps from a civil war quilt kit.
