Bookhou at Home is doing some freehand piecing in rough, hand-dyed fabrics, that has a pojagi feel although she is not using double-side-finished pojagi seams. I'm wondering for such omni-directional scrap use, why not sew the pressed unit onto a straight-grain piece of thin cotton, and use the attachment seams to secure the raw edges. The piece would hang straight, at least.
Each patch and stitch added by the maker was like a prayer of good will that would enfold and carry the gift. Women adapted chogak po for clothing, sometimes combined with quilting, to "wrap" and dress their loved ones. Many surviving patchwork wrapping cloths from the Chosŏn period have never been used, attesting to their preservation as reminders of the affection and blessing of their maker.
