The best of #InkTober, a 31-day challenge where artists show off on Instagram

Six years ago, artist Jake Parker decided to challenge himself by completing a new ink drawing every day in October. In order to hold himself accountable, Parker made the experiment public, posting photos each day online.

#InkTober was born. 

Now, six years later, over 1 million photos have been posted on Instagram alone using the hashtag. The rules of participation, as Parker set them, are simple. 

1) Make a drawing in ink (you can do a pencil under-drawing if you want).
2) Post it on your blog (or Tumblr, Instagram, Twitter, Facebook, Flickr, Pinterest or just pin it on your wall.)
3) Hashtag it with #InkTober
4) Repeat

From famous animators to self-taught amateurs, artists around the world are now participating in #InkTober. 

Let's see what creative sketches some participants have come up with.
