This Halloween, I made my son a Hatty Hattington costume, a character he chose from the BattleBlock Theater video game. We were both pleased with how it turned out.
The hat was papier mache using a Quikrete cement forming tube from Home Depot and a styrofoam wreath (for the brim) from Michaels. Before I clued it to the top of the cardboard box, I laced a bike helmet (using cording rope) from the inside to the top of the box for stability. The 12" x 12" cardboard box is painted white and scrapbook paper cutouts are glued on. I cut a hole for him to see out of and glued in a white sheer fabric.
I sewed the cravat from
this pattern using a top I found at the thrift store. I would make it longer next time.
