I did these in part because I'm gearing up to do a very tiny Kickstarter for Wychwood chapter 1! (The pre-launch page is here, for the curious: https://www.kickstarter.com/projects/559623833/wychwood-chapter-1)
I wanted to try making a holographic or metallic sticker because I find them super fun and cool (and haven't done it before), so I spent some time doodling up ideas for a design. The top one is the final, and the second one is just a secondary idea I whipped up for fun!
