Balloon wreath: You could use #'s in place of the Letter for milestone Birthdays. Like 1, 16, 18, 21, 40, 50, 60, 70, etc. & hang it for the party or for the entire birthday month...it could even be a keepsake/memorial gift for a birthday present! @Danielle Hartz Strickland
Think it would be cute with fall colored balloons.. or even red white and blue for 4th of July. :) ballon wreath - used 288. Buy an 18-inch straw wreath, leave the plastic wrap on it and use greening pins (also called floral pins — they’re sort of U-shaped and can be found in the artificial flower section at craft stores) and just pinned the balloons all over the wreath.
