I'm doing a Craftsy class on sketchbooks right now, and I've just completed the lesson on cross-hatching. Something I'm not very good at - I lack the patience and discipline. But practise practise practise and we might see some progress.
I'm also thinking of doing a Sketchbook Skool course some time and I got a sample lesson and received an email last weekend about creating a narrative in your art journal, by drawing an object that summarises your day. A great idea, as I often struggle trying to think up about something to draw.
So I sat out in the sun last Monday afternoon, after a morning spent on the Dublin mountains, and drew my boot.
