I found a great place to buy 100% wool blankets too: Alpaca4less.com

I bought a king sized Alpaca wool blanket for my California King bed, which is a bit larger than a traditional king sized bed, and it fits amazingly well. We have about 20-25" tucked under the mattress and it's still long enough to comfortably cover the pillows. It's wide enough to drape 12-15" over the sides of the bed too.

I like sleeping in the cold so I crack a bedroom window even in the winter. I turn into a furnace when I sleep, much to my wife's delight, 'cause she hates the cold. When the temps drop into the 60's, she's breaking out the thermals.

This wool blanket, along with a sheet and a very light top blanket, keeps her toasty and me cool. I got her a mattress heater for Christmas a few years ago that she uses every night, but it's down to the lowest setting with this wool blanket.

The offering from this company are hit and miss, so if you see what you want, grab it, it may not be there next time you check. They ran some amazing discounts in December, so I got a bunch of Alpaca wool hats for Christmas stocking stuffers. Every one of the five people that received a hat raved about how comfortable and warm the alpaca wool is. I guess I should have got one for myself!
