Élena Nazzaro has challenged artists to draw every day in May, and several artists have taken her up on her challenge.
I first became aware of this challenge through the Every Day Matters group (that I have often mentioned on this blog). It looks like a wonderful challenge and the participants seem to be having a lot of fun with it. Unfortunately, this year, I will not be able to participate. However, there is always next year.
There is a Flickr group set up for this challenge that you can view here --> Every Day in May
Also, here is a partial list of participants for your viewing pleasure:
