I was occasionally having an issue with bleed through to the back of the page (when I used heavier layers of colour), but I've come up with a solution. I first tried clear gesso, applying it after the black marker work was done (and completely dry!), but it added a bit more 'tooth' than I wanted. I guess I could have lightly sanded it, but instead I tried using matte medium. That works beautifully! It still gives the page a slight texture, but that adds some extra interest to the page (in my humble opinion).
I'm really loving Joanne Sharpe's "Draw Your Awesome Year" online class. I'm learning a lot of new ideas and trick to improve my drawing and art journalling. It's not too late to sign up...all of her classes are 'forever access' too which means you can keep going back and reviewing the lessons as you begin each new year! How awesome is that!
I've never considered myself much of a 'drawer', but I am really enjoying this process! What a great way to build my skills.
