I am taking the free online class by Julie Gibbons called Mandala Magic. It is quite therapeutic in the same way I imagine zentangling is.
This is my Day 2 Mandala
I used a windsor and newton journal and coloured the mandala with inktense blocks. The journal held up quite well - the page buckled slightly but the colours and sharpie pen did not bleed through.
Happy thanksgiving to those in the USA
