Since you've reacted to processed wool (e.g., sweaters), I'll assume that surface allergens (like dander) aren't the problem. Most wool comes from sheep -- do you know whether you're allergic to sheep? How about cashmere? usually made from goat hair. Do you know whether you're allergic to goats?

I wonder if you are allergic to wool or to something that the wool had on it. I think allergies to wool are pretty rare. Wool is pretty good at holding on to dust and dander, it gets trapped in between the fibers. My DS decided he was allergic to wool or down because that was what his bedclothes, but a good cleaning stopped the sneezing and sniffling.

Could you buy a pair of new smartwool socks and see if you have a similar reaction?

Another experiment would be to sample a lotion that contains lanolin to see if it triggers a similar reaction. An allergy to wool, is usually to lanolin.

Also, if you are allergic to sheep wool you could, perhaps tolerate alpaca. I live in wool, but I cannot wear angora(angora is rabbit and I am allergic to rabbit dander). Here's some great, vibrant striped alpaca blankets. http://purelyalpaca.com/collections/alpaca-blankets/products/alpaca-bed-blanket-striped

I looked at the Cotton Collection linked above and it has 25% wool in it.

Look at Denali "blankets", The 60x70 is a very good size throw. It's fleece, which normally I avoid, but theirs is thick and luxurious. I have the "Chocolate Stripe" on my sofa, and I love curling up under it to watch TV or whatever.

Just reading about that old blanket made me sneeze! I would seriously consider that you might not have been allergic to the wool itself, but perhaps it had been stored without cleaning/washing for a long time? Same with the wool sweater? I think others have given good suggestions about how to figure it out...oh, and I actually can't wear wool sweaters because they make my neck itch, but cashmere (the better quality kind) is fine. I never seemed to have the same reaction to woven wool, like a wool jacket or pant or skirts, so experiment and see how you react. My allergy is to contact, not to proximity.

From another thread,

Throws

I got some faux Hudson Bay fleece blankets for our lakehouse bunkbeds from Landsend. I don't see them anymore but they have others that might interest you:

If you like Pendleton's Hudson Bay stripe, try Hudson Bay in Canada -- the exchange rate is in Americans' favor now, as a bonus : )

Acrylic "cashmink" (!) throw, on clearance at the moment

Cotton version

A "luxe" cotton version

Polar fleece version one, and version two, and version three

There is also Woolrich without the wool, but they're pretty pricey for what they are.

Didn't know that -- this is definitely a contender. Thanks!

I see that some of their cotton blankets are 100% cotton, while others are 25% wool.

I don't know if I'm allergic to sheep, and I don't know how to (easily) learn the answer. We had goats when I was a kid, and I hate them, but hate isn't allergy -- I used to care for them without trouble. Of course, I didn't cuddle up with them either. 'Specially that big billie Nutmeg; I used to throw his food at him and RUN 'cause he'd threaten me with his horns.

I think allergies to wool are pretty rare.

I've read the same thing. I read that many people who think they have a wool allergy actually have a problem with the "scratchy factor". However, wool gives me badly weepy eyes and constant sneezes, so I think I have a real allergy. For the life of me, I cannot remember whether my skin turned pink or if I had hives.

Were the items in question clean? Well, my husband's old blanket, probably not. But my grandmother's sweater was one that she wore very regularly -- so I know she would've had it cleaned regularly. Regardless, I don't want to set myself up for an item that requires more-than-average cleaning.

Buying a pair of wool socks as a test is an excellent idea. Why "smart wool"?
The 60x70 is a very good size throw.

Enough for a foot-of-the-bed item, but I still prefer a full blanket.

My
allergy is to contact, not to proximity.

I think I could say the same thing. I've never had any problem with other people's clothing, and surely other people have worn wool around me.

I'll take a look at them -- and the other blankets suggested here. Thanks so much for the ideas!

Apologies for sending in the links to throws rather than to blankets -- that's what happens when I'm in a rush, argh...
