Months later, while perusing IKEA, I happened upon a shadowbox and remembered that I also needed a ticket showcase. So I picked up a Ribba.
Then, a couple weeks later, I had the time to execute. I started by taking the frame apart and marking a line I wanted to cut in the top.
We had used the oscillating saw to cut the slit in Jen's shadowboxes, but I was alone, and steadying the frame and the saw was not going to work well. Instead, I used a drill and methodically increased the bit size. In between, I used an exact knife to cut/stab between the dots and through the outer and inner frame.
He was coming home from a 30+ hour workday event, so he didn't see it. He liked it upon direction. I haven't decided on it yet, but Jen also used glass etching cream to write "ADMIT ONE" and outline Mickey Mouse on hers. It looks awesome and I can't prove it to you because I didn't have the foresight.
My favorite thing is how cool this will look as it evolves. Every ticket is a memory, and they peek out from behind each other. It's easy to adjust, too - I kept shaking it like an etch-a-sketch when I wanted something else in the front.
