Attempting a DIY project for your wedding, large or small, can be disastrous. Here’s why: DIY designs require creativity, labor, and attention to detail. Since they’re so time-consuming, you may need extra help from friends or family and everyone can burn out fast on the job. Even if you’re committed to the project, things might not go as expected. Often seemingly easy tasks turn into lengthy jobs that cost more money than you think and end up looking sloppy or amateur.
