All energy and attention has gone to the Tri-C JazzFest for the last several weeks and I did almost no drawing or sketchbook work. Well, the rust settles in pretty quickly, my friends.
The only way to work it out is to work it through. Do the rusty-joint work to get it out of your system. It's this way in everything: writing, exercise, painting. It's OK. Whatever you had comes back quickly enough and you move on to whatever you're going to have after more practice. Which now includes a talent for picking up after a dry spell.
