The pale blue pencils are great to use to start a sketch - then you can work towards the final with graphite.
I may just go out in the field - maybe - and try my new pencils and new Stillman & Birn sketchbook out. Then again...I’m not much for sitting outside in the heat, humidity, and bugs. We’ll see. May just observe, take notes, and take photos to draw and paint inside later. (We can’t all be plein air painters!
