You could totally make these pumpkins with those decorative pumpkins and some artificial flowers from the craft store. You could then reuse these every year and wouldn't have to worry about the mums drying out!
This looks like it could be a super fun kid craft. I would just draw a tree template on paper and let my four year old fill it in with fall colored buttons!
All of these have definitely got my fall decorating juices flowing! I am probably going to start pulling out my fall decorations this weekend.
What is your favorite item to decorate with for fall?
