I'm starting to sew again after a few years hiatus and have been trying to learn about batting. There have been a lot of discussions about this and one issue is whether or not to pre-wash or not and does it shrink. I would love to see some pics of a finished quilt, large or small, with batting not pre-washed, before and after it was washed, so I can see examples of the puckering that happens when the batting shrinks a little. Anyone have any pics or links where I might see what a difference it makes? TIA!!
