Here is the sketch:
For my card, I used the Studio Calico Penny Arcade card kit. The gnome, mushrooms, and sentiments, and red button are all from the Penny Arcade kit. I didn't use this kit very much when I first received it because I didn't want to fussy cut the various stamps, but I picked up the matching dies this month and now I'm a happy stamper. What did we ever do before dies? Clearly, I am addicted to them.
I used Copic and Spectrum Noir markers to color Mr. Gnome in. The mushrooms were stamped with Tropical Teal and Pure Poppy ink, and I used Summer Sunrise for the inside of the "yay" stamp.
