I created this tutorial when paper flowers were newish and realized that I needed to transfer it over to my new blog! So here you go! :)
Fold your petals at the base so they overlap each other a bit. I used hot glue to secure mine. You can also just staple them! The I went to the opposite end of the petal and rolled them up to get the petal and folded over and blooming look. Play around with the amount of folding you want and what looks best for whatever layer of petal you're working on.
Continue building with the remaining petals until you get the fullness you're looking for.
Finished! And repeat, repeat, repeat! Have fun building beautiful flowers!
