I'd like to try doing eyepiece sketches using the white-on-black technique (been using graphite so far). The local art store had a pad of the Strathmore Artagain (60 pound, 400 series) paper I've seen recommended, but they didn't have much of a pencil selection.
So I went online and ordered 2 black and 2 white Conte' Pastel pencils:

And a set of 4 Conte crayons:

Did I get the right stuff? They all feel a bit 'chalky'.
