I used some of the same materials as I used in my latest "biotechnology" art journal spread (found here), because this book went to a person also in the field of biotechnology.
I was thrilled when figured out this word play: The biochemistry book had the title "Genes & Gene Expression", which I used here. I painted a thin layer of gesso on top of the word Gene (not to much, so the word is still visible underneath) and I wrote Art on it, so it became "Art Expression". Perfect for an art journal! :)
This was the first book cover, that I decorated, but it won't be the last. I already promised to make another one as a gift. And of course I need my own. :) I hope that the next time I will remember to take a few pictures during the crafting. The first one is always a bit more style searching and experimenting and therefore, taking pictures is often forgotten. :)
