The last 2 nights that she has slept in a wool cover she has woken up with red marks. The first tiem it was just one thing line around her thighs... Thinking the pressure from how she was laying cause it was only on the front and she sleeps on her tummy. But last night I had her in her OS LL cover and she has red marks around her legs and waist that aren't going away! More like a reaction to the matterial (or something on it) than pressure cause this cover isn't very tight on her... I would assume it's something on the cover, not the wool itself since she doesn't react like this to everything, but how do I strip a wool cover????
