Jake Parker started the INKtober initiative in 2009 as a challenge to improve his inking skills and develop positive drawing habits. It has since grown into a worldwide endeavor with thousands of artists taking on the challenge every year.
The Rules are as follows:
1) Make a drawing in ink (you can do a pencil under-drawing if you want).
2) Post it online
3) Hashtag it with #inktober and #inktober2016
Note: you can do it daily, or go the half-marathon route and post every other day, or just do the 5K and post once a week. What ever you decide, just be consistent with it. INKtober is about growing and improving and forming positive habits, so the more you’re consistent the better.
