I found the craft on Alpha Mom. She does this craft with children who are a bit older than M and their pumpkins look great!
First I took my square piece of orange paper.
Then I folded it three times on the diagonal.
You can then unfold it and cut along all the creases toward the centre leaving the middle uncut.
Then you will cut out "flower petals" like this.
Later I found it easier to keep it folded and cut out the "petals" all at the same time, making sure not to cut right to the middle. Then I unfolded it and cut along the creases.
The next step is to punch holes in all the tips and the very centre.
Make some leaves and put holes in these too. Thread this onto your pipe cleaner.
