This is my finished product and I am quite happy with it.  The Zentangle is copied on a transparency and layered over a base butterfly I watercolored with yellow h2o paints and then I layered a smaller transparent butterfly on top of that.

Now, on to my Christmas cards that I hope has got a zentangle in it as well.  I already have planned the layout and need to get busy.  Just wanted to share this butterfly effect with you as I think it is a very meaningful project and fun to do.

May your days be bright and your tummies full this Thanksgiving holiday.
