Sketching Supplies

I am currently experimenting with many different media and am never sure what I want to use on any particular occasion. This is a sketch of most of the art supplies I bring when I go out sketching. I have a watercolor set in addition to watercolor pencils (which I’m still figuring out how to use), four different pens (a red, blue, and black needle-point pen and one brush-like ink pen), a small set of oil pastels (which I have recently discovered to be good fun – as are crayons), vine and stick charcoal, a set of graphite pencils, and at least one sketchbook (preferably one for dry and another for wet media). A goal of mine at the moment is to challenge myself more with charcoal and graphite, which are media that I do not use often.
