My small sketching kit...

 

Here's my sketching kit. Aquabee 9in.x6in. 93lb. Sketchbook, small Windsor & Newton palette, 3 brushes #12, #6 and a small one I hardly use and a plastic handled brush that has a reservoir to hold water. (Brushes cut down to fit in the bag.)  Uniball and Faber-Castell waterproof pens. Mechanical pencil, kneaded eraser, a few clips and a tube of white paint. A small bottle to hold water, a plastic water bottle cut down for a water bowl,  a sponge and a bit of paper towel.
