Before I began teaching from my 'Stash and Smash' book I practiced on my friends and got some great feedback. It also helps with your timing - class and instruction time can go by so quickly you have to be very aware or you leave students with an unfinished project. Not a good thing.
I hope as an artist you have found your own kindred spirits to share your art and your vision with. Articrafters is always welcoming new members, some of them recently requested a Zentangle refresher course. As I was looking through some of my Zentangle drawings I found a few I wanted to share with you. My strings (the starting point for most zentangle drawings) always seem to turn into funky creatures. I love making a few swirly marks and trying to decide what they should become. The creatures don't seem finished unless they have drips, tears or dots!!
