That's SEW cool

Challenge: Crate a postcard with some sewing. 

I love this - but I don't think the wavy edges of the woven strips will make it through the mail, and I am not sure that I want to give it up!.

Things got a little easier once I reminded myself that it was "with some sewing" and did not need to be 100% fabric nor glue-free!

Can You Tell What I Have Been?
