Excuse my ignorance, but what is the difference btwn soap and detergent?
My first few felting projects took forever to felt (in washer with laundry soap) and when fellow knitters saw them they suggested I use a few drop of dish soap in the water and POOF everything felted so beautifully and so much quicker. Their explanation being that the wool needed the agitations of the bubbles in the dish soap as where most laundry soaps are low suds. I typically run stuff through a cold water delicate rinse to get rid of the soap. Since I am not felting anything I wear I don't worry about a little bit of residue.
