This prompted me to try to come up with a unique postcard for her (though she never asked for one in return). I decided to make one – my first ever fabric postcard. I have read instructions for them now for years, but had yet to do one. Here two sites with good instructions: How To Make a Fabric Postcard - Directions Plus... and How To Make A Fabric Postcard DebR Style.
The one I made for Intueri is 4in X 6 in.
I received my postcard from her this past Monday. I mailed hers the same day. I hope she likes hers.
