To make this easy decorative piece you will need~
First clean out all the insides of the pumpkin. Make sure to get all the seeds and goop out. (you could spray with a bleach/water solution to keep it fresh for longer)
Then cut the flowers and place in pumpkin. Make sure to write your greeting on the outside and done!
Besides the bleach part (if you do, do that) this is a child friendly craft and could even help with cutting practice. It's interesting to see what color schemes my kids come up with and how focus they are on placing the flowers.
