Talk about stitchy goodness for inspiration and adaptation, thanks to my DD, who is REALLY good at finding these things, I found a blog called Agence eureka, which is chock fill of great vintage printed material.
It’s written in French, but the important thing is the wonderful images. I found things, such ad this chart from an arithmetic book, that could go straight to needlepoint. There were more pictures from textbooks, illustrated magazines, children’s books and games, and advertisements. There are even tons of vintage alphabets to adapt.
Just think how fun it would be to do a version of this snowman in needlepoint. I think I’m in stitching heaven!
