Simply determined.

Each week for a year, I’m designing a shirt and releasing it on my Threadless store. This is the design for week 26 and marks the halfway point for my 52 Shirts project.

My oldest became a teenager this week, so it was her turn to work with me to design a shirt.* We had everything completely planned out, but when I finished it, neither of us liked it.** While we sat at the dining room table trying to improve the design, she doodled on a sheet of paper “Watch out world, here I come.”

“What’s that?” I asked, pointing to her doodle.

“I don’t know. Sometimes, you need a plan B, right? It’s always good to have a plan B.”

It was, indeed, time for plan B. I took her phrase and shaped it into an exclamation point.

Norah’s determined. She’s one of those kids who just won’t quit. Smart, strong and kind. “Watch out world, here I come” seemed perfectly appropriate to celebrate her 13th birthday.

You can purchase “Watch out world” from my Threadless store in a wide range of colors. And happy birthday, Norah!

* Now that Norah’s shirt is done, we’ve completed birthday shirts for all of Team Wertz — Me, Jill, Ryan, Liz and now, this shirt for Norah. It’s been fun — and challenging — partnering with each of them on their shirt.

** The original shirt was going to say: “I’m afraid of clowns, snakes and being like everyone else.” Alas, choosing a typeface we both liked proved to be impossible.
