Planning a Halloween Slime Party? I’ve got something fun to share with you! I designed this free Halloween Slime Party invitation just for my readers, and I’m excited to offer it as a customizable Canva template and a ready-to-print PDF. Whether you’re hosting a spooky slime-making event for kids or a family-friendly Halloween gathering, this invitation will set the perfect tone for your slimy celebration!

Invitation Details
This invitation is about 5.5 x 5.5 inches (14cm x 14cm)—it’s designed to fit standard 5.5 x 5.5 inch envelopes.
I wrote the poem on the invitation and then designed the invite with Canva—that way you’ll be able to customize it before printing or sharing it if you’d like to!
Double double toil and trouble, fire burn and caldron bubble
Join us at the witches’ lair, for a party if you dare.
We’ll brew up some lovely slime, you’re guaranteed a gooey time!
Wear a costume to disguise and guard yourself from witchy eyes.
Don’t forget to let us know, or we’ll feed you dead man’s toe!
It’s a playful way to get your guests excited for the party, with just enough Halloween vibes to set the mood. Perfect for a kids’ party, family fun night, or even a classroom Halloween event.
Customize It in Canva
If you want to add your own personal touches, I’ve got you covered with a Canva template. You can easily:
- Pop in your event details like where and when, and who (RSVP info).
- Tweak the text and colors if you want to change things up a bit.
- Use it digitally or print it—whichever works best for you!
Canva is super easy to use, so even if you’ve never used it before, don’t worry. Just click the link, log in (or create a free account), and you’re good to go!
Ready-to-Print PDF
If you’d rather keep it simple, I’ve also included a printable PDF. Just download, print, write on your event details, and you’re ready to send them out. It’s perfect if you want a low-tech option.
How to Send It
Once you’ve downloaded your invite, here are a few ideas on how to get them out to your guests:
- Mail them in a fun Halloween envelope (or add some spooky stickers for extra flair).
- Hand-deliver them if your guests are close by.
- Go digital by sharing the file from Canva through email or social media.
Whichever way you send them, these invitations are sure to get your guests pumped for some slimy fun!
