I believe that this is the first one of our Mystery Challenges I've actually participated in since we started them last summer! Shame on me! It was so fun and definitely a challenge. You should play along with us at Stylin' Stampin' INKspiration!
I managed to use 5 of the 6 challenge elements on my card.
I started with Hearts (1). There are heart shaped balloons in the Balloon Builder stamp set which is in the 2016 Occasions catalog. I stamped one in each of the challenge colors (2): Bermuda Bay, Wild Wasabi, and Watermelon Wonder. Next I outlined them with Dazzling Details for a Glitter (3) element. Once that was dry, I cut them out using my Paper Snips
The card base is a 4-1/4" x 11" piece of Watermelon Wonder card stock scored and folded at 5-1/2". I layered a 4" x 5-1/4" piece of Wild Wasabi embossed with the Lucky Stars embossing folder (4a). Next I cut a piece of Whisper White card stock to 3-1/2" x 4-3/4" and embossed the bottom with one of the folders from Fun Frames (4b). I stamped Happy Birthday (5) from the Balloon Builders stamp set in Watermelon Wonder and added two Bermuda Bay Candy Dots.
I didn't want a stark difference in my layers, which I feel happens with Whisper White, so I sponged some Wild Wasabi ink around the edges in hopes to blend the layers a bit. I added my balloons and there you have my challenge card!
There are some super adorable cards from the design team today. Check them out and play along with us!
