We made a quick trip to the Pumpkin Patch for pumpkins.
I did have him talked into this slightly more reasonably sized pumpkin, but it had some bug problems.
I was fortunate that Nathan chose a simple costume this year. No pattern. No ridiculous fabric fluff. Very little sewing.
Mario only needed to have some big yellow buttons glued onto a pair of thrifted overalls and a cool hat made of fleece. I followed this tutorial, but increased the measurements to fit his head.
