After downloading the InkPad app on my iPad, I found that I could draw these on the computer as well. Learned a lot of things to make my drawings faster too. My Mood Board ended up being used mostly for color inspiration so I think I can use it to make another pattern using the style of the images.
When designing my pattern block, I found it easier when copying the elements from one edge to the other, to group those elements once they were exactly 1000 px apart, that way I could adjust one side and see what happened on the other side as well.
I couldn't decide if I liked the dark or light background so I included both. Now I want to make supporting patterns! So many new things to try!
