If you make lots of quilts, you have lots of small left over pieces of batting. Seems like a waste. I have been joining small pieces of batting together for years.

I join low loft (usually cotton) batting together by machine. Using a walking foot, select the largest setting you have for zig- zag stitch and sew the batting together. My machine has as wonderful undulating stitch, it works too.
