Everything a build needs
From the first reference to the photos after the con.
- Feed
Show the build
Post the work in progress and the finished look, credit who made it, shot it and wore it, and pin the builds that blow you away.
- Pattern
Cut the pattern
Every build gets its pieces to make or buy, steps to tick off and a tape-measure that shows how far along you are.
- Stash
Know your stash
Fabric, foam, wigs and paint in one drawer, with quantities and shop links, ready to use in your next build.
- Deadlines
Beat the deadline
Due dates per piece on one calendar, and an agenda that tells you what to work on tonight.
- Con ticket
Get con-ready
Count down the days, see who's going, pack by section and meet up in the event chat.
- Jacket
Earn your patches
Finish builds, keep your streak and collect badges to sew onto your con jacket.
