I've started washing every single piece in my stash. I started doing to because once I came up with an idea, I would pick out the fabric, wash it, line dry (we don't have a dryer) then iron. By the time it was all done, I had moved on to somethingelse. This way I can just grab fabric from my stash, give it a quick pressing and on with my quilt project.
Now every new piece of fabric coming through the door is washed before it makes to to the sewing room.
