Can you believe that Halloween  is literally right around the corner? It’s a time of the year that I truly do think about and plan for, always.

First off, they make fun, inexpensive costumes to make and secondly, they’re totally unique and different.

Do I have to be a balloon expert to make this DIY Halloween costume?

Not at all. In fact, I actually learned how to make this costume from Ballon and Paper. Jamie is a seasoned balloon expert and here to share all her tips with you. She broke it down for me in a way that made it not too hard to do. 

You can actually make this costume following her simple tips and advice in a very short amount of time.

However if you need extra help and don’t want to source all the materials yourself, Balloon and Paper has just come out with DIY Balloon Costume Kits! 

How long will the balloons stay inflated?

That’s probably the million-dollar question for this costume. BUT, there is a way to be prepared even if you don’t have the answer. Balloons will inflate and deflate depending on the weather so there isn’t anything that you can do about that.

But you can be prepared and ready for any balloons that might pop or fly away by carrying around a bag with some simple repair supplies in it.

What if the balloons pop while trick or treating? 

We can’t promise that won’t happen because we can’t control the unknown! However, if you’ve ever made Halloween costumes, you’ll know they can never be 100% fool proof.

The best thing is to be prepared! Pack up a hand pump, some extra balloons, and some glue dots or clear packing tape, and you’re easily prepared without stressing out over anything. If a balloon pops then you know that within a few short minutes, you can repair the costume and resume the trick-or-treating.

(My other mom tip for you is to talk to your child beforehand about the possibility that a balloon may fall off or pop. That way they’ll be prepared as well and you can easily spring into action and get it fixed without causing them to be overly stressed.)

Everyone loves cute unicorns, right? So this costume is certain to be a hit. Get ready for your child to be stopped every few seconds to pose for pictures or to even answer all the questions of all the other kids.

This Halloween, your child is going to make a statement! Luckily, with just a few supplies and elbow grease, you can complete this DIY Unicorn Balloon Halloween costume without putting in a ton of effort.
