Personal sketchbooks are a great way to practice your drawing skills without pressure. I have been trying to keep a sketchbook with me during the day so I can take advantage of those rare quiet moments (usually waiting for my kids). The best part is that nobody usually sees my sketchbook, so I am free to try new things and make mistakes. I also use my sketchbook as an idea book for future paintings.
I highly recommend starting a personal sketchbook (especially if you are planning on coming to some of the Summer Sketch Tuesdays).
*plus there are so many lovely accoutrements: notebooks, pens, fountain pens, brush pens, inks, pencils, pastel pencils, portable watercolor sets, nifty pencil bags…
