Yep. actually allergic. I can work with and wear yarns that are 20 - 30 % wool, but I wouldn't want to go any higher. Have you ever seen a really bad poison oak/poison ivy reaction? That's what happens to me. Also allergic to lanolin, makes my eyes swell shut.
I learned at a very young age that I had to read the ingredients on things like lotion, hair conditioner, lip balms, stuff like that.
I'm not allergic to silk though! Or chocolate, or coffee, or ice cream... It could be worse!
