Well before she met Maya, Sadie was a cosplay and costume-making enthusiast. She knows her way around a sewing plan. As Maya is a champion of bad stunt ideas, Maya quickly started working on costumes that could survive a skydive. Then costumes that could incorporate a parachute harness, then customized harnesses, and finally going all the way into parachute rigging to make customized costume parachutes.
Here she is making sure her skills survived the transition to the pony world, and also creating and testing a sweet gift for a friend.
I was kind of scrambling for an idea for this one, to be honest.
