Not sure we actually need a reason to have flower crowns in our lives. I think every day is worth of flowers and better yet, flower crowns.
BUT if you must have a reason to have a flower crown really any event or celebration coming up is a reason to flower party.
If you are trying to figure out a fun activity to have at your party FEAR NO LONGER as we have the best, flower activity for you and your guests to walk away wowed.
