with 20 yards, you could try all kinds of things! How big are the rectangles? Are they big enough to be pillows? or small enough to be pot holders?
They make me think of picture frames...
I love the floral pattern in your closeup picture -- might be a good one to use to practice FMQ -- do a quilt sandwich with a nice plain fabric as backing, and FMQ following the pattern in the print. Use a contrasting thread in the bobbin, so that the backing side is really your finished work.
It's really a rather odd print, isn't it. A big flowy skirt maybe?
