I hearted her shop, she has way, way cute cards (and the ribbon caddy is genius). But one thing, if she's open for advice, is that in my opinion she ought to take pictures of the inside and back of her cards as well as list the size dimensions of the card and if the listing includes an envelope. In wondering myself what card I would like to purchase, these things came to mind and will probably come to the minds of others. By far, your mom's cards are probably some of the best I've seen on Etsy but it's so competitive on there, those details could make all the difference. Best of luck to you and your mom!
I am so envious of all that beautiful ribbon, all nicely organized!
