If there was one pattern that owned our needles this year, it was the Sailor Slippers. Honestly? Over Christmas it felt like every second customer who walked through the door was making a pair. The famous felted sailor slippers were everywhere. We’d ring through wool and someone would say, “Yes, I’m making the sailor slippers.” Again. And again. And again.

And honestly? We get it.

Sailor Slippers are a felted slipper pattern by Annie Germai

that knit up quickly, look wildly impressive, and make the kind of gift that people immediately put on and refuse to take off.

They’re worked flat, seamed, and then felted to size which means the real transformation happens in the wash.

They’re not quite “my very first project ever,” but they are an excellent skills-booster. In one pair you’ll practise Increases, Decreases, Casting on mid-project, Seaming (hello heel shaping) And blocking + felting

Because they knit up quickly, they’re also very forgiving. If something looks off, you can rip back and fix it without spiralling.

Ask us how we know.

Jenny knit our shop sample and described them as really quick and easy,  the kind of project you can cast on with confidence and finish before you lose momentum.

She did redo the heel seams a few times to get them perfectly lined up (worth it). One very smart detail? Stripes on the soles. Not just cute – they make it much easier to line up the side seams when you’re finishing.

After blocking, she even took a razor to gently shave off some of the surface fuzz. It cleaned them up slightly not a dramatic difference, but a nice finishing touch.

The Yarn

For the slippers, Jenny used and we have been suggesting Cascade 220  knit double  and it’s honestly the perfect choice for this project.

Cascade 220 is a 100% non-superwash wool, which is exactly what you want for felting. Because it hasn’t been treated to resist shrinking, the fibres grab onto each other beautifully in hot water and agitation, creating that dense, sturdy fabric that makes these slippers feel like real footwear not just thick socks.

It also felts down evenly and predictably, which is very reassuring when you’re intentionally shrinking something by 5+ inches.

And from a shop perspective? We love recommending it because it’s reliable and accessible. We keep Cascade 220 in stock all the time, and there are so many colours to choose from. Whether you want classic nautical stripes, bold brights, earthy neutrals, or something a little unexpected for the soles, you’ll find a combo that works.

It’s one of those workhorse yarns that quietly does exactly what it’s supposed to do especially when you’re throwing it into hot water on purpose.

Let’s Talk Felting

The slippers need to shrink about 5.5 inches in length total and this is where things get… adventurous.

Jenny highly recommends felting in a washing machine if you can. A proper hot cycle makes a huge difference. Her building’s shared laundry only partially runs hot before switching to cold, and after the first wash they’d only shrunk about 2 inches. At that rate, it would’ve taken another 2–3 paid loads.

So she pivoted.

Hand felting with hot water and dish soap? Extremely effective. Also extremely tiring. After an hour her arms were done.

And then… innovation happened.

Yes, there is photo/video evidence of the slippers in a KitchenAid mixer with the dough hook attachment. No, we are not officially recommending this method to the public. It does not work with the paddle (too big, potentially motor-destroying). The dough hook technically works, but it sloshes water everywhere and is slower than hand felting.Did it give her arms a break? Yes.

Is this sanctioned advice? Absolutely not. 🫣

If you’ve been wanting something practical, slightly addictive, and deeply giftable this is your sign.

You might not stop at one pair.
