I was a dedicated stamp collector in middle school (geek). Even in this digital age, I still feel drawn to a pretty stamp when I find one. Apparently there are other quilters who are fascinated by stamps and mailing things.
Regard the concept of a fabric postcard. Seriously. Google it and you'll find books about them, You Tube videos, and countless images in Pinterest.
I guess it's fun because the projects are small and there's the adventure of finding out if it can effectively travel the postal system and wind up at its destination.
I sent myself one. It arrived. Now what?
