Yes, it's true. I just found a site called Handknit Heroes - Teen Superheroes in Fabulous Handknits.
Here is a teaser blurb from the site, and a link to get you there:
"Imagine you’re a teenager, and you have some… special powers. Maybe even super powers. And one day, at a sleepover, your best friend in the whole world tells you—you’re not alone. So begins the adventure for a couple of teenagers, a single mom and yarn shop owner, and a whole bunch of hand knitted fun. Handknit Heroes is the first graphic novel for knitters. Each issue features a great storyline with knitting superheroes, terrific artwork, and a beautiful (and easy) knitting pattern."
