12 inch wreath (or whatever size you want)
100 balloons (25 red, 25 yellow, 25 white, 25 black, you will need more for a larger wreath)
ribbon for bow
When I got almost around, I left a section without balloons for the ribbon, below is what it looked like before tying the bow on.
I wrapped the ribbon around a few times and then made a simple bow. I used floral wire to tie the bow to the wreath.
And here is the finished wreath!
