U.S. Army sleeping blankets made by Family Heirloom Weavers!  At a great price!
One of the more common variations seen in surviving U.S. blankets is the use of white warp yarns.  Grab one of these reproductions if you want a neat blanket without standing out in the ranks.
Choose either a copy of the Pvt. Snyder blanket (left), which most closely matches the typical blankets most are used to, or the Pvt. Quimby blanket (right), which is woven with a unique twill weave.  Each comes with the US stitched in.
