A topic discussed over and over... just received this interesting YouTube from "Just get it done quilts" where she makes three different quilts each with different pre-washed (or not) methods and shows the shrinkage and crinkle results.. Proof there's quite a difference depending on whether you pre-wash or not. I'm sure it would differ depending on various fabric, batting or thread choices, too.
No right or wrong here - just lots of options
