After doing quite a few sugar skull prototypes, I have finally used the design in a book binding project! I plan to fill this 8 X 8 inch journal with pictures of my parents and momentos from Arizona.
Something that worked well here was using a copper-colored acrylic ink to paint around the artwork, rather than leaving the Canson mixed media paper a boring white. Sealing the colored pencil sketch with acrylic gel medium gives the cover an additional glow.
While I am generally happy with the way that this book turned out, I've concluded that I may need to use a thicker binder's board if my goal is to do an elegant job of hiding a recessed battery.
In this model, the majority of my focus was on getting the artwork to line up with the circuit. If I could go back and do it all over, I would position the hole for the battery another half inch away from the corner to provide more wiggle room for creating a flap to conceal it.
I had fun soldering the LEDs to the copper tape, but one of the LEDs that I selected for the eyes stopped working after I sewed the signatures into the book!
After bending the cover a bit, it worked again, but now my front cover has a slight bend to it.
