Technically speaking I haven't done much with my pictures except for printing them out to give to grandparents. I have been working on a photobook on my canvas, but have never finished it.
Besides pictures of my kids, I take pictures of the baby bedding my mom makes. http://www.facebook.com/LullabyGardens You can tell the pictures I took in the beginning and the one's she's taken with her point and shoot. Even though I know I can still stand to improve greatly on how I take these, they are good enough for her to sell enough to keep her busy full time.
The closest my pictures have come to making me a profit is on my Etsy site. Crafty Chic Studio by CraftyChicStudio on Etsy I've only sold one thing so far... lol I'm hoping it's because I don't have time to promote it, and add more sets as opposed to the fact that people don't like what I do. It's my goal to make some "photo" invitations and greeting cards to add to the site, but I haven't had time yet.
