I have been using Procreate for several years now. I thought it was time to learn a few new tricks and this class was awesome! My favorite tip was the reference tool. I always keep a visible layer with my colors. But that takes up an area of my workspace. With the reference tool I can keep the colors handy (plus other things, like other parts of the illustration).

I also loved the value check tip. I ended up making shifts to color with the black layer visible and then checking to see what color I ended up with. Very cool tip! 

Thanks, Stephanie! As always, you have great work methods and its always inspiring to watch you work.
