Have you seen this board on Pinterest - Art Journal - Hand Lettering Ideas/Tutorials curated by Sierra Hennessy? Lots of good stuff here!
I love the (above) Hand Lettering created by Lori Vliegen, host of the Elvie Studio Blog. I found her on Pinterest.
Check out Lori's blog - and the Art Journals Board too. And if you find other Pinterest boards focusing on Art Journal or Hand Lettering, please share.
