I use 100% wool batting for all of my personal use quilts and they are used and washed regularly (Quilters Dream wool).

For future projects, only use temporary, water soluable adhesives, made specifically for free motion quilting. The only one I can recommend, based on personal experience from when I had a sit down longarm, is 505. It doesn’t gum up on the needle and washes out with the first wash.
