House rule
A generator can make a finished knight. It cannot make the pattern, the foam cut, the primer coat and the wiring, in order, each dated when it went up. That is what a build log holds, so the process is the proof.
AI-generated images are not allowed on Cosnet. Editing your own photos is fine.

A generator gives you the last frame. Not the first three.
One pauldron, followed from the pattern on the mat to the con it was built for. Everything below works: drag it, tap it, filter it.
01Log the build
Log one costume from the first sketch to the finished shoot: the materials, what they cost and where you bought them, the hours, and your photos under each stage. Put the link in your bio, or print it as a build book for the judges' table.
It opens without an account or the app, and the printed copy carries a QR code back to every photo, full size.
02Learn the craft
Craft is one place in three parts: Builds for your own build log, guides written by the people who made the thing, and a directory of places to buy foam, print a part or book a photographer.
A guide gives the technique, the level, the hours, the materials and every step with a photo. Anyone can write one.

Yes. Joining, posting, following and messaging cost nothing. Some competitions charge an entry fee, and you see it before you register.
One page for one costume: the materials and what they cost, the hours, the wearable weight, and your progress photos under each stage. Anyone with the link can open it without an account, and it prints as a build book with a QR code back to the page. You can keep a build private until it is ready.
Any image made by an image generator, or changed by one beyond recognition. Editing your own photo is fine: cropping, colour, retouching. See one that breaks the rule? Report it as an AI-generated image from the post's menu.
Yes. Make your account private, share a post with followers only, decide who may tag you, and block anyone. Blocking works both ways.
