I ran out of lead drawing a bunch because I had no pen to finish anything.
So in some wild act of desperation I broke open my old pen, removed the cartridge, punctured it, added water, shook violently, dumped into a bottle cap and then proceeded to dip a sewing needle into the make-due ink remnants to draw with.
Yeah. I did all of that. Drew with a needle. Out of it I got only two sketches worth of ink-like-substance, so, update incoming. You know where to look.
