I have created Icad challenge #1 and #2. Icad 2016 (Index Card a Day) was created by Daisy Yellow. You can find more Icad challenges here. Each day there is a prompt and there is a weekly theme. The object is to create a little piece of art on a 4 x 6 index card everyday. Daisy Yellow has extended this challenge through July. You can start anytime.
What challenges are you working on now?
