I remember when I was a kid, Mom gave us pillow cases that had designs stamped on them. Normally you would embroider them, but she gave us ink pens of some sort and we traced the pictures, then she ironed them to set the ink.
I think we made them for The Grandmas or The Aunties.
That’s all I know about it, LOL!
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.
