I have two vintage quilts that were made with wool. They're from the 50's and were originally store-bought, covered in a solid green fabric, front and back, stitched in a box pattern much like a down comforter except wool. They were recovered in the 80's but have never been actually quilted. The wool is quite thick, maybe 2", and the quilts have always been dry cleaned, not washed. They are quite heavy, still soft, and wonderful to sleep under if you like the heat way down at night as I do.
