I have been given a link to a new website,Agnes , and it is full of the most beautiful embroidery. I love this image from the welcome page.
There is a folder on this site with the title "Louis's Embroidered Postcards".
There are over 2000 embroidered cards in this collection and It is interesting to see that photographs had embroidered details back then. (The cards are rotated not all up there at once.)
A lovely way to waste some time.
