Party at The Pit – The Ultimate Creative Party Experience in St. Louis!

Looking for a birthday party or group celebration that’s hands-on, unforgettable, and totally unique? Party at The Mash Pit is where creativity meets celebration! From age 6 to 106, guests get to design and create their own custom apparel or product—with expert help from our in-house designers. Everyone leaves with a personalized item they made themselves and memories that last a lifetime!

How It Works

 Design Time (First Half)

  • Guests choose from a variety of products like t-shirts, tote bags, pillowcases, hats, and more.
  • Our team guides them step-by-step to create their own custom design.
  • Want a little extra flair? Guests can collaborate one-on-one with our graphic designers for a personalized masterpiece.

Party Time (Second Half)

  • While we handle printing and production, the party is all yours!
  • Eat cake, play games, open presents, or snap selfies in our creative studio space.
  • Before you leave, we’ll snap a group photo with your finished creations and send it to you to remember your special day.

You create. You celebrate. We print & clean up! 🎉
