I had a Silhouette cut file that cut a keyhole in the front of the A2 card base as well as a keyhole outline. I embossed a woodgrain A2 panel and then cut a keyhole into it as well. I put a piece of vellum behind the keyhole and thought that it would be fun to have it peek through to see the "unbirthday" party.
I stamped and heat embossed "A Very Merry Unbirthday to You" out of view of the keyhole. Fitting all the characters I wanted provided a bit of difficulty and I didn't like the way the peek looked, so I decided to add another white cardstock panel behind the vellum so the scene behind the keyhole wouldn't show though.
I die cut all the images from the three stamp sets listed above and copic colored them. I inked blended a bit of a background with distress oxide wilted violet ink. I then adhered everything in place and finished with a sentiment from the Alice stamp set. Thank you for stopping by!
