Piecing them together works - and it does not need to be a neat straight seam - just so it is not bunched up - and the smaller pieces you could do a quilt as you go quilt - My MIL does many of those; she throws nothing away until it is in need of a magnifying glass to see it! lol Have a great day! You can also make stuffed toys, or pillows from them; they make great stuffing.
