You remember last year I was in the pink team for our end-of-year organisation-wide party? This year I’m in the blue team. As far as clothing is concerned, that’s not going to be difficult (whereas the pink was a considerable effort).
However, the silliness aspect? There are eight people in the team. I offered to make bow ties or shoe bows. No, no, they’re not going to be fancy. Pinking shears on single-layer fabric, that’s all. I’m raiding my deep, deep stash to haul out some fabric that dates back to high school sports uniform days. Venerable. Blue. Sturdy. And, I hope, enough!
