I find the idea of calling cards completely fascinating. I have been reading up about them in some of my reprints of Victorian etiquette books (yes I have more than one book on Victorian etiquette... Doesn't everyone?). Often they were simply dropped off at a friends house (handed to a maid or other servant) to show you were thinking of them and had stopped by. The cards in my collection that don't appear to have names actually have the name hidden under the picture (which lifts up).
Well I should get back to studying. Oh, in case I forget, I should mention that I have created a facebook page for my Etsy store. I just thought it would be a great way to keep everyone up-to-date on my latest patterns, and give sneak-previews at some of my works in progress. I also plan on sharing neat vintage sewing and millinery resources I come across. If you are interested feel free to like my page.
