When I started publishing my pencil drawings as notecards, I had no idea that printing cards in color would become affordable.

I had no earthly idea that I would ever become an oil painter.
SURPRISE!
I had no idea that someday I would be selling a package of 4 cards for $10 instead of 10 cards for $5.
SURPRISE!
All of these notecard designs (and many others) are available here: Cabinart/Store/Notecards.
