I spent this last weekend with my eldest daughter, Jennelle, and we discovered the art of Zentangle and after some research decided to give it a try.  The following is the artwork we created.

The pens we used were purchased at a rummage sale in Jennelle's subdivision and were drafting pens with very fine points.  We each bought a set of these pens and after checking the internet were surprised to find out they were valued at over $100 a set.  Jennelle's cost 3$ and I paid only 2$.  What a find.
