I prewash the fabric with soap. I have not prewashed the batting.
I have not enough.
Finishing up on quilt #3 and fabric for quilt 3 is about to go in the wash.
Maybe I will hold of all of the colors are similar so no need to worry about bleeding. They are from the same manufacture and I love the old quilt look so shrinkage is not a concern. I might just wait until some others have posted. before I start that load.
