The "written" side of the postcard started with a Japanese calendar fabric that I currently owned and thought would be a fun addition to this quilt. I fussy cut the months and then added a pieced red/white/blue/white strip to mimic the printing you see on postcards/envelopes. I added a simple black divider and then on the right side fussy cut "stamps" (above, it is the flower) and then used a text print below the stamp to mimic the writing on a postcard.
I love rainbow quilts, so I added a solid border around each postcard bundle and then I had a completed top, which I intend for this to be a fun wall hanging.
