I first did this at a December bridal shower. all the attendees got to paint their own ornament and that was their party favor. They were all gorgeous! Everyone enjoyed it (men and women).
The last couple of years i have been buying the bulbs at after Christmas sales and making my own ornaments for the next year. One year I did lime green the next year I did orange and gold. Both trees were beautiful. I got so many complements. (as you can see I am not a traditionalist). LOL. Have fun.
