Jason Momoa and Jack Black Sweaters: What Really Happened Behind Those Viral Crochet Looks

It started with a single photo that broke the craftier side of the internet.

Jason Momoa and Jack Black, two of Hollywood’s most beloved "chaos agents," sitting side-by-side in matching, oversized crochet cardigans. They weren't just any sweaters. These were vibrant, "granny square" style masterpieces that looked like they were plucked straight out of a 1970s living room—or perhaps a very cozy corner of the Minecraft Overworld.

People lost it.

The image immediately went viral, sparking a wave of "hexi-cardi" fever that had hobbyists dusting off their crochet hooks and casual fans wondering if the Aquaman star had secretly spent his downtime between takes learning the difference between a double crochet and a slip stitch.

The Truth Behind the Twinning

So, did Jason Momoa actually make these?

In short: No. But he was the mastermind. During a press tour interview for A Minecraft Movie in early 2025, Jack Black spilled the beans on how the "bestie" moment came to be. About a month before their media blitz, Momoa called Black with a very specific proposal.

"I'm gonna make us sweaters," Momoa told him. "What's your colors?"

Black, being Black, didn't hesitate. He requested blue, green, and purple. Momoa’s response? A simple "Done," followed by the click of a hanging-up phone. While the quote made it sound like Momoa was the one pulling the yarn, he later clarified that he commissioned them from a specific artist he’s been championing for years.

The hands behind the hooks belong to Tosha Marie, the artist behind Treat Yoself Crochet.

Marie is no stranger to Momoa's wardrobe. She has been his go-to for custom crochet pieces for a while now, including a purple cardigan he wore to read a CBeebies bedtime story that previously sent the knitting community into a tailspin. For the Jack Black collaboration, she spent about two days on each garment. That is an incredibly fast turnaround for a handmade "hexagon" style cardigan, a feat she shared on her Instagram following the press tour explosion.

Why Everyone Is Obsessed With These Hexagon Cardigans

If you aren't a "yarnie," you might not realize that these aren't traditional sweaters. They are hexagon cardigans, often called "hexi-cardis."

They are fascinating because of how they're built. Instead of knitting flat panels and sewing them together, you crochet two large, L-shaped hexagons. When you fold them, they magically become the sleeve and half of the torso. You join them down the back, add some length, and boom—you’re a movie star.

• Jack Black’s Version: Deep blues, forest greens, and royal purples. It perfectly matched the indigo tones of his character, Steve.
• Jason Momoa’s Version: A much louder palette of pink and purple, mirroring his "Garrett the Garbage Man" character’s flamboyant 80s aesthetic.

The appeal isn't just the colors. It’s the subversion. Seeing Momoa—a man known for playing a literal god of the ocean and a galactic bounty hunter (Lobo)—embracing the "softness" of crochet is a vibe. It’s authentic. It doesn’t feel like a corporate marketing stunt; it feels like two guys who actually like each other wanting to wear something fun.

The Minecraft Connection

You can't talk about the jason momoa and jack black sweaters without talking about the movie they were promoting. A Minecraft Movie is, by definition, a film about crafting.

The costume designer, Amanda Neale, leaned heavily into textures like wool and weaving to make the cubic world feel "homespun." While the crochet sweaters weren't part of the actual film costumes (Momoa wears a pink fringed leather jacket and Black wears a classic Steve indigo shirt), the sweaters became the unofficial mascot of the press tour.

They represented the "crafting" spirit of the game in a way a standard suit and tie never could.

Can You Get One?

The "Momoa effect" has had a tangible impact on the DIY community. Since those photos dropped, searches for "hexagon cardigan patterns" have surged on platforms like Etsy and Ravelry.

If you want the exact look, you have two real paths.

First, you can support the original artist. Tosha Marie (Treat Yoself Crochet) occasionally sells finished pieces and patterns, though her commissions usually fill up the second a celebrity is spotted in her work.

Second, you can make it yourself. The pattern is surprisingly beginner-friendly. Most creators on Reddit’s r/crochet suggest starting with a basic "Granny Hexagon" tutorial. It’s essentially just one giant repeating stitch.

Actionable Next Steps for Fans and Crafters

If you’re trying to replicate the jason momoa and jack black sweaters vibe, here is how to actually do it without getting overwhelmed:

1. Find the Pattern: Search for "Granny Hexagon Cardigan" on YouTube. Creators like Passioknit Kelsie or Annah Haakt have tutorials that break down the exact geometry Momoa and Black were rocking.
2. Pick the "Momoa" Palette: Look for "bulky" or "chunky" weight yarn (Size 5 or 6). For the Momoa look, you want variegated yarns that include magenta, lilac, and plum.
3. Support the Source: If you aren't ready to pick up a hook, check out Treat Yoself Crochet on Instagram. Even if her commissions are closed, following the artists that celebrities actually use helps keep the "slow fashion" movement alive.
4. Embrace the "Garbage Man" Aesthetic: Remember that Momoa’s character is all about 1980s nostalgia. If the sweater feels a bit "too much," you’re probably doing it right.

These sweaters weren't just a fashion choice; they were a moment of genuine friendship caught in a high-pressure Hollywood cycle. Whether you're a gamer, a crochet enthusiast, or just someone who enjoys seeing Jack Black look cozy, there's no denying the "hexi-cardi" is the real star of the 2025 press season.
