I have found Pinterest to be both a vexing and inspirational source of ideas for teaching art. There are some resources that are more predictable and well thought-out, but then they tend to be equally bland and overdone.
I started curating a few pages years ago – everything from baking and sewing, to teaching music and art. Take a look. Amongst this wildly random collection you might actually get a clearer idea about my thought process.
Keep exploring… I’ll keep adding pages gradually.
