I have been visiting my son and his family the past week. I actually taught his daughter zentangle when she was just 8. Now she is 10. She wanted to do a tangle page with circles. So we drew circles with ramekins from the cupboard and then took rulers and drew lines hollibaugh style. Here is what we got done before I left. She loves gel pens - the brighter color the better. So I was not at all surprised when she got out the gel pens and started using them instead of a Micron. She will finish it and show it to me later. I have mine done and still some shading to do - I will post the completed piece.
