Family treasure About 6x4 ft ….I would love to display as a wall hanging
I'd check into having it actually framed at shop with acid free matting/paper and matte glass(no glare). This will protect it and keep it from yellowing.
you can get anything framed; hanging it may stretch it out
How about a quilt hanger?
Gotcha. Buy a remnant or piece of fabric. Lay out the tablecloth. Lay the fabric on top of the tablecloth. I would strategically pin in place. Then carefully fold the tablecloth so that you can see the pattern and hang up. I would refold and rehang periodically as it may stretch out. Another idea to use. Place it on your dining room table, then place a piece of glass or plexi glass over it.
