Well anyways my dads business partner gave me his old set of these very nice colored pencils, about .. 60 of them, STABILO

I've never worked with this kinda median before. I'm used to graphite and some ebony. I've played around with charcol.

but these pencils are VERY soft, it has a very similar feel to a soft charcoal pencil which I don't really know how to use lol..

anyways..does anyone have any tips to go about working with them?
