Ask the Laundress
Do you have a product that helps take the itch or scratchiness out of a new cashmere or wool sweater?
I recommend washing and soaking the scatchy items a few times and see if they soften up as there isn't much else you can do to soften the stiff hairs in the yarn. You could use fabric softener, but it isn't great for the yarns because it puts a smooth coating on the item. If the itchiness is unbearable however, that is an option.
