Hi Moonpi,
I didn't make any myself, but for all the artists, I say THANKS! :D
They are pretty small, but to think the postcards are 4" x 6", and there are people working on
inchies and
inchie-plus items ...which are quilted and embellished 1" and 1-1/2" squares! Type
inchie into Google and all kinds of blog links pop-up on it. Folks are making collages of the wee quilted bits, doing swaps for chains of them, etc.
The postcards were introduced to me when I did a swap/exchange after signing up at

I hear some quilters are doing these smaller projects for color studies and pattern/technique tests, but some just like the break of working at a smaller scale.
...and they really do go through the mail!
