Thanks for the suggestion Jim! I do not yet have a time-tested sketch gear, but this is what I've been using lately. Or rather: part of what I've been using.
Tip of the day: if you're planning to add color to your sketches, make sure to use waterproof pens like the Faber Castell PITT series or the Prismacolor Premier. Unless of course you want to play with the effect of the line getting deluted... which I plan to do very soon.
Let me know by commenting here or on Facebook at facebook.com/regulascheifeleart. And keep those ideas for sketching coming!
