Party Favors

It’s always good to have something to say “Thanks for Stomping By” for your party guests. You can make gift bags with these dinosaur stamps.

Now it’s time to fill the bags with favors for your guests. There are some really great food and non-food items you can give. Let’s start with the food options.

  • Create you own gift or snack bags with dinosaur themed labels
  • Dinosaur egg candies (use round candies like chocolate covered peanuts, troli sour eggs, Easter egg candy, etc)
  • Dinosaur snacks (pretzels, goldfish, cereal and more!)
  • Dinosaur gummies (best bet is finding them in store at Walmart)

Non-food items are endless when it comes to dinosaurs as they are such a popular item for kids.

Plus regular party favors that aren’t dinosaur-themed are always a hit
