The Creative Challenges 50 is a blog/website I started a while ago and is still in progress.
50 challenges to get your creativity going. No time limit, you go at your own pace in the order you want. You can do as little or as much as you like, the important thing is what YOU enjoy. You can also share your artwork for these challenges on thecreativechallenges50 Facebook page.
