This is how I cut the scalloped flap.
I love these flowers from the Squigglefly store. I used Copic markers and added Glossy Accents to the creases and the center. I love the dew drop effect that I achieved. I hope you give this a try...I enjoyed making this more that I thought I would and I can't wait to make some more.
Have a great week and I hope it's full of sunshine :)
