I generally wash all my fabric, with the exception of precuts or kits. I like to wash in cold water, then let the dryer go about half cycle, then while slightly damp I iron the fabric, it's much easier as it is evenly damp so ironing goes fairly quickly. If I don't catch the fabric before it dries, when I'm ready to start a quilt, I set up my ironing board, use a spritzer bottle with just water, then iron as usual. Since I don't have a big board, I've found that turning the ironing board around so that the wider section is up front, that also helps.
