I made a bunch of fabric postcards for Christmas and everyday, and if they sell well I'll make more, because they're a really fun way to feature pretty fabric. Here is one that I did for Christmas, and here is one of my favorite "everyday" cards that would also be great to send from a Hawaiian vacation:
I have a few different designs for both Christmastime and any time. They're for sale now in the shop, Etsy.com/PandorasPurses! They are $5.00 a piece plus shipping, and as of 11/1/15 cost about 71 cents to mail within the United States. Any questions, let me know!
