If you have not tried zentangling, give it a try it is so fun and freeing! There is lots of instructions and ideas all over the web. Pintrest was my inspiration today :-) I used Sharpie black fine point pen, and also their black fine point marker.
I should have some show and tell next week from the retreat. I have lots of projects to work on, most of them are quite simple so I hope to get tons done!
