February is a month where I could go broke buying birthday cards. Whether you're an artist or just someone who dabbles in watercolor from time to time, you too can paint your own greeting cards.
You can buy a box of blank greeting cards, I've been using the Strathmore Cards. They come in boxes of 10, 20 and 100 and include an envelope with a pretty deckled edge.
I purchased a box of 100 cards with envelopes from Cheap Joe's Art Stuff online. That way I always have them handy, ready whenever I need one.
Sometimes I paint a bunch of cards ahead of time, leaving the inside blank so it can be used for any occasion as I need it. Or if I realize I need to drop a card in the mail that day, I can quickly paint one up and send it off.
