To start, measure the decorative pillow form. Add 1-inch to both measurements and cut two pieces of natural linen fabric to this size. With right sides together, sew around three sides of the pillow cover, leaving the last long side open.
Turn the cover so right sides face out. Slip a piece of paper between the top and bottom to protect the back fabric. Using the iron-on fusible web and scraps of fabric, create a stamp. The one I made had a white backing fabric about 2- by two 1/4-inches in size and then an inner face about 1 3/4- by 2-inches. Sandwich the tape between the layers of fabric and the pillow front at the top right corner, making sure no tape is visible, then cover with a paper towel or light cloth and use a hot iron to secure in place.
Next, make an “AIR MAIL” sticker from blue fabric (you can paint it later) and a dividing line from ribbon, and apply them in the same manner as above. Now you’re ready to decorate and personalize your greeting.
I used typewriter font letter stamps to print “CARTE POSTALE” across the top. You can too, or try “POST CARD” or “SPECIAL DELIVERY.” Then, using a black indelible marker, and two circle templates (a bottle cap for example), I created a round cancellation stamp, and only printed the city and date in block letters. Squiggly lines finish off the canceled stamp.
Using some white acrylic paint, I painted white block letters for the “PAR AVION” or “AIR MAIL” stamp. And sketched in a simple shape for the stamp face.
Finally, use the black marker to address the card like you would a postcard and write your simple greeting. When the paint is dry, remove the paper and insert the pillow form into the cover. Fold under the open seams and pin together. Hand stitch the bottom edge to close.
