#inktober is the an immensely popular art challenge for October. Started by Jake Parker in 2009 to improve his inking skills and drawing habits, by 2018 Inktober is a worldwide community event with professional and beginners alike sharing their daily ink.
I do love using ink, especially the dense and waterproof black India ink (which I seem to have lost) So far I have been using coloured EC Drawing inks that I bought for a project last year (I didn't end up using them). The drawing inks don't have the same intensity as pen ink, so hopefully I'll find my black ink before October is over. use #inktober2018 to view the varied offerings of inktober 2018.
