I used this same stencil (mini mod spiral) on the umbrella last week and LOVED it, so I knew it would look super cool with some distress inks - I used two, Peacock Feathers and Twisted Citron, and love how it turned out!
I stamped the uber large 'happy birthday' from Mama Elephant's Birthday Wishes set and traced it with a black spica glitter pen - next to impossible to see in the photos, but cool up close. I added some MFT black polka dot designer paper and carried it over to the inside along with one of the small sentiments and both sizes of candles. The candles were stamped in VersaMark for a light accent.
Those fun balloons, from WPlus9's Unforgettable set, are on the envelope; I created a post-it note mask and sponged each with the same distress inks as the card.
