It's definitely a celebration! Check out Nichole Heady's blog to find out what delicious new colors are being revealed for this March 15th release. Yummy.
I have to say it's a pretty amazing feeling to have something I created come to life in such a interactive way. I have attached a sneak peak of one of the images for my very first Papertrey Ink stamp set named "It's a celebration."

This party flag graphic is my personal favorite, with the options of using any of the three patterned flags or the solid flag image to create your very own unique design. Mixing up the colors is an option as well since all the graphics are separate stamps! Dot, star, and stripe patterns are used throughout the entire set in the various images so that coordination is a snap. The flag string could be an optional element as well, by using your own choice to string or ribbon as a substitute and arranging the flags to create a more 3D effect. Individual Flags were designed so that they rest along the string with only a slight rotation. "It's a Celebration" is extremely versatile as with all of Papertrey Ink stamps. ;)
I created all my stamp images in Adobe Illustrator which is part of the Adobe Creative Suite. I use Photoshop and InDesign in other aspects of my design life as well. Since my background is graphic design, and I'm passionate about what I do, designing for Papertrey Ink is a dream come true. With the freedom to create as I'm inspired, the sky's the limit.
Starting with a theme idea with some heavy brainstorming, I dive into creating images and sentiments that represent that particular theme. In the case of "It's a Celebration", the flag images where the first that came to mind.
