I participated in inktober twice and made a lot of inked artwork after that as well. To create my inked art, I use a mix of different tools. The most important are a colored pencil for the base sketch, fineliners to ink, and moleskine paper which doesn’t bleed through. You can find an overview of all of the tools I use for Inktober on my Amazon affiliate page. I also have a detailed tutorial about inking on my Patreon, which you can also purchase from my tutorial shop!
