These two sketches were both done on the soft covered vegan Italian made Cass Art sketchbook. It has recycled paper inside which doesn’t look like or behave like recycled paper.
I sketched this in 3-4 minutes while sitting in the Phoenix Community Garden in London, and then took a lot of reference photos with my phone.

Later on I added watercolour to the sketch:

This is a 5-7 minute sketch of the stalls in Spitalfield market done with a sepia Faber Castell Pitt pen on the same Cass Art notebook.

I bought this sketchbook on a complete whim, because it was relatively inexpensive and I liked the look of it. I liked it so much I returned later on and bought a second sketchbook with a different cover colour.
