FROM A single nib, thousands upon thousands of artists can be drawn into the fold.

That nib, as it began, belonged to Jake Parker, a Utah-based artist who said he “created InkTober in 2009 as a challenge to improve his and develop better professional habits.

“InkTober just started out as a way to motivate myself to become better at drawing in ink,” Parker tells The Post’s Comic Riffs. “I wanted to do a bunch of ink drawings for practice, but I needed a way to be accountable for it, otherwise I’d get frustrated and move on to something easier. So I announced the challenge and invited people to do it with me.”

That first InkTober didn’t attract a swath of participants, but artists did express support for his effort. And in the six years since, InkTober certainly took hold — as a shared experience in which many artists around the world follow Parker’s same committed schedule: Create at least one ink drawing each day of October.

The results are now widely shared on social media, with such hashtags as #InkTober and #INKtober2015. Parker — whose new book, “The Little Snowplow,” with Lora Koehler (Candlewick Press), lands next month — shares some of the offerings on his Instagram and Twitter accounts.

“I couldn’t be happier,” says Parker, who notes that the campaign still pushes him personally. “The pressure is on for me to do it and do a good job at the challenge each year. However, it’s evolved for me from being just an exercise in getting better. It’s become a platform for me to explore story ideas, and to push my style and artistic voice.”

Now, The Post’s Comic Riffs would like to spotlight InkTober in this space, so if you hashtag your art #Inktober and #comicriffs on Twitter and Instagram, we’ll pick some of the illustrations to showcase in this space.

And as Parker looks forward, he says: “I hope it’s something that keeps going, and keeps inspiring people to pick up a pen and tap into their creativity.”

We hope you, too, pick up a nib or brush yourself this month and create. Happy InkTober!
