I really fancy one of these to fry jumpers on to keep their shape and size. Even when washing wool jumpers by hand I find that the bottom line of knit often shrinks in and needs to be stretched out again. I do dry them flat but need a way to keep the bottom the right size. Board seem to be an outdated old fashioned thing and I can’t find one for sale anywhere. Any tips where to get one or how to stop wool jumpers Shrinking around the bottom?
