Thanks! I would think that a hot iron on anything would be effective.
I remember those stamped pillowcases. I have some that my grandma embroidered in the early 1900s. You can still buy them, I think, through Herrshners.
I have a few that my Grandma Anita made for me. They’re so beautiful, I just look at them, versus drool on them, LOL!
There is one that is an embroidered, ‘Southern Bell’ with umbrella and pretty hat, and her ‘skirt’ is crocheted lace and the pillow case is cut out in that area.
I’ll take a pix later. Fond memories of ‘crafting’ with my Grandma, so THANKS! :)
