I used the Balloon Bouquet punch to punch out multiple colors of balloons. I used a Journaling Pen to draw all the strings for the balloons. The glittered washi tape was a Sale-A-Bration from last year. I used Stitched Rectangles for the mat & the image.
I kept the inside simple so there's enough room for all my co-workers to sign the card. The finished size of this card is 5x9.
