How to throw an easy DIY Harry Potter party for $100


Turning 26 years old should mean I want to throw a fancy, dignified adult party — well, not for me. For my birthday, I wanted to cross something that has been on my bucket list for a very long time — I threw a Harry Potter themed birthday party (also, this was my husband Jose’s gift to me he — helped with most of the DIY in this blog)! Of course, what’s a party without all my mature and sophisticated adult friends?

Now, there was little problem that most muggles like me encounter … I’m not Harry Potter rich and I’m living on a budget! I can’t wave a magic wand and money will appear. After doing much research through YouTube, Pinterest, etc. I found the most budget friendly ways to throw a Harry Potter party.

Here is a breakdown of how I threw an HP party (for 20 guests) without breaking the Gringotts bank. Mind you, most of this was DIYing, so you’ll need to take time to do most of these things.

Platform 9 3/4 door cover 


White vinyl table cloth – $1

Sponges for brick shapes – $1

Red and brown paint – $2-3

We spent a bit more on a customized stamp and wax because we know we would get more uses out it after this DIY like for our business or sending letters to family and friends.

Write Harry Potter’s address on the letters, but replace with your guests’ names to give it a personal touch!

Hogwarts castle walls and banners

  • Ask family or friends if you can borrow or buy an item off of them
  • Check out the Dollar Store for the best and cheap Halloween decor
  • Look at Offer Up for any materials you need
  • I went to Goodwill on 50 percent Saturdays where I found a lot of things I needed like the potion bottles that were about $1-$2 each

I want to thank all my friends who came to my birthday party, especially Caitlin O’Hara and Alex Araiza who took photos and videos for me to put on this blog. This was the best birthday party I’ve thrown. I was afraid it wasn’t going to come together because of the budget, but it came out “bloody brilliant”!
