Awhile ago, I bought some Irish wool that I got for a sweater from an online store. When I got the wool, I realized that it was too scratchy so I set it aside. Recently, I decided that I would use it to make an afghan, but I'd like to soften it up a bit once I am finished. I am in my third of ten skeins, so it'll be awhile before I am done.
I have read that hair conditioner helps, but most are highly perfumed. I have also read that glycerin works, as well as vinegar.
