The easiest fabric postcard to make, IMO, is what I created today. I made eight of them and took them to the PO to be hand-stamped after I had afixed a self-adhesive stamp and rubbed it in with the back of my nails. I know, from experience, some will arrive locally, tomorrow. (click on both photos to view)
I sent the sparkling fairies to thank my grandchildren for my birthday gifts, the pencil prints (Kaffe Fassett design) with the cakes to thank for other gifts or to wish a happy birthday to people here and far away, and the baseballs to Evan who put up our paper when we were gone.


First, with a rotary cutter, cut a front, a back and a piece of flannel, all 4 1/2" x 6 1/2." I used an antique stamp to print Post Card, but writing it is equally nice or better. I ironed on the cakes with something like Wonder Under. Next, stack, the pieces and pin: the flannel on the bottom, then the back and front, their good sides together. Stitch all around 1/4 " from the edge (leaving a two-inch opening mid-end so that you can turn the pieces after clipping the corners). Press after turning. Now stitch 1/8" from the edge all around which will close the opening. I used white thread, and Sharpies to color where I did not want white lines. I used a gel marker to write without the bleeding of ink. I wish I could move more slowly to give the ink time to dry!
