I put this pattern together after learning some tips on building patterns in Illustrator from my pal Marisa. It really upped my pattern-making game, I think!
Up until now I've been constructing them by hacking away with the "offset" filter in Photoshop, and often having to flatten my document more than I'd like. This time, I sketched separate assets in photoshop and imported them into Illustrator to use with the new pattern tool. I moved them around until I had a working sketch of what I wanted to create, and then I went back into Photoshop to complete the art for each individual asset. Then it was just a matter of re-importing the new assets and I was done!
