Speaking in general, media fandom women do a fair number of crafts, as well as other fannish projects. In some fandoms, they do some really difficult art, and sometimes you see other projects from engineer-type women.
However, it’s guys who usually decide to build the Enterprise bridge replicas, or the full-sized mecha that light up and move. And the more guys in a fandom doing cool large scale projects, the more projects tend to arise. Guys inspire each other as well as being competitive.
The modern iteration of My Little Pony fandom is probably 75% guys, so they build videogames and snowhorse statues and elaborate orchestral compositions. They are a ridiculously active and productive fandom segment.

As you’ll see, he has also done a balloon life-sized Dalek, a balloon Ash from Evil Dead, a balloon Alphonse from Full Metal Alchemist, and a giant stingray between two palm trees. Also costumes for people to cosplay in, and hats, and room decorations. 9 pages of balloon art.
