The card base is white cardstock, and I cut a light blue panel the same height but slightly narrower. I used Lawn Fawn's Blue Skies stamps and dies for the balloon, banner and clouds. I notched a strip of white cardstock for the sentiment.
All the pieces were colored with Prismacolor colored pencils and blended with mineral spirits. I added some glitter to the banner with a clear Wink of Stella brush pen. I colored the heart with red Spica pen.
