Grids are your friend AND your foe. I had issues trying to get my pen tool to snap to the custom grid, turns out you need to disable "Align to Pixel Grid" and turn on "smart objects". That was the most frustrating part of this lesson. However, I had loads of fun making this pizza, and creating a GIF to make it more fun. I think I could work a bit on colors, but overall this was a fun project!
