I won't explain this piece. But I did it as homework for the Inktense class I have been taking online with Jessica Wesolek. It is a wonderful class - if you are intrigued by Inktense pencils - Jessica is starting up a new session of this class on March 15. Visit her website for all the details and to sign up.
I almost forgot to add that the tangles used are from my ebook, The Tangles of Kells.
