Embroidered Vintage Linen Whitework Handkerchief Pouch

This vintage handkerchief pouch was pre-owned and probably handmade by the owner. It is made of an off white linen fabric, maybe a type of homespun. Hand embroidered abbreviated initials HDKFS on the flap done in white and flanked by small white flowers. Embroidered scalloped edges along the flap. Clean inside and out. The last two photos show small thread breaks which are overall, pretty inconspicuous. Laying flat as in the fourth and fifth pictures, this measures about 15.5 inches long and 9.5 inches wide. The pouch itself is approximately 9.5 inches square and the flap is about 6 inches.
