Up for your consideration is a 100% virgin wool blanket in medium brown.  These are in really good condition.  Much like the Pendleton brand, the wool in these is soft, not too scratchy, so they're perfect for a bed topper.  They are twin size and measure around 85" by 54" but being a natural material they can vary few inches either way.

These make excellent bed or picnic blankets.  I use some as a filler for a futon mattress which made it nice and warm.  One customer uses them as a filler in her quilts.  These could also be used to make period-correct Civil War-era bedding or clothing.

These wool blankets look barely used, and I think they have been recently cleaned as there doesn't seem to be any odors. They come from a smoke-free and pet-free environment.  Let the photos be your guide.
