Tips for Creating Your Weird DIY Costume

Tip Explanation
Start with a sketch Having a clear vision of your costume will help you stay on track and avoid any mid-project panic.
Gather your materials Before you start, make sure you have everything you need. There's nothing worse than realizing you're out of hot glue when you're halfway through your masterpiece.
Take your time DIY costumes often require a lot of patience and precision. Don't rush through the process, or you might end up with a wonky costume (or a wonky finger, if you're using sharp tools).
