The other day I stumbled upon this picture on Pinterest with no link. Sad but true. However I did find the blog which containes the actual tutorial on how to make a balloon wreath. I think the amount of balloons needed depends on what size wreath you use. Also, you can add a bow, pipe cleaners, birthday hat etc.
Birthday Balloon Wreath!
First you need balloons. Lots and lots of balloons.
(2 bags of 72 count…the 1 1/2 to 2 inch sized balloon. If you want it more full and to fill the outside edges, use more)
