Strathmore offers four workshops over the course of the year. They cover many things – basic drawing, mixed media, art journaling, watercolor, and more. You do have to register to access the classes, but they are all free.
I was trying out some new paints (Qor) and, out of curiosity, decided to follow Workshop #3 – Watercolor Sketching & Journaling by Gay Kraeger. The workshop is meant for beginners and aimed at using watercolor in a journal or sketchbook. This is a 2014 workshop, so it can only be accessed until December 31.
Note: I was using different colors than Gay, and doing some things meant to test the paint colors, rather than following her instructions directly. Her work is much better than mine!
The classes for 2015 are already up, and the list for both 2014 and 2015 can be found here.
