If you want a colorful card, the Happy Patterns Decorative Mask makes it easy to add your favorite colors wherever you want them. You get 4 stencils with all-occasion patterns, and as you can see I used the mask with the dots and happy stencil to make my birthday card.
My card base is Daffodil Delight Card Stock that I layered with a piece of Melon Mambo and Whisper White. The dot colors are Daffodil Delight, Melon Mambo, Night of Navy, Pear Pizzazz and Bermuda Bay. My happy is also Melon Mambo ink and a piece of Melon Mambo 1/4" Cotton Ribbon was also added. My birthday sentiment, from the Age Awareness Stamp Set was cut out with a Project Life Framelit and a bit of Daffodil Delight ink was sponged around the edges to give it a bit more dimension.
Tip: To keep your mask from moving use a few pieces of tape to hold it into place while stenciling.
