Knitpicks Mighty Stitch yarn review

By now you probably all know about my undying love for Knitpicks. They are a great source for budget yarn that isn’t 100% acrylic, and I love ordering basics from them–things like everyday sock yarn, solid colors, and yarns I need in larger quantities. Their Shine and Comfy lines are two of my top picks for non-wool yarns.

But they do also carry 100% acrylic. I stopped buying acrylic yarn in general several years ago because I don’t like the way it ages. It pills, it doesn’t breathe, and exposure to heat and light can change the texture of the yarn and making it sticky (I actually just wrote an article on this subject for Piecework’s website). Anyway, it’s not my go-to yarn anymore.

I wanted to make a duster sweater a few years ago, however, and could not afford the amount of yarn I needed in a natural fiber. What’s more, the yarns I would need to order, I couldn’t touch in person in advance. I’d have to buy online, and with my sensitive skin there’s no way I was going to spent $150 on yarn without knowing it was next-to-skin soft.

Knitpicks offered the perfect value pack: 2 skeins in each of the seven colors I needed for a total of about $75-85 (the package is no longer available, so I can’t confirm the price. I bought it in 2017). Individual balls sell for $4.99.

I’ll tell you more about the sweater later, but here’s what you need to know about the yarn and how it worked up.


Gwyd approves.

Mighty Stitch is a worsted weight yarn that is 80/20 acrylic/wool. It’s cloud soft, very light, and comes in 100g balls (about 208 yards according to the ball band). It comes in a wide variety of solid colors, most of which are quite bright (the yellow I ordered, Canary, looks a bit muddy to me, but in photos, next to the other colors, it looks vibrant without edging into highlighter territory).

It’s recommended for use on a US7 or 8 needle (4.5-5mm) or an I, J, or K crochet hook. I used a US7, and I must be an incredibly loose knitter because the fabric is not very dense at all. It drapes really well.

So now that we’ve looked at the stats and the pros of using this yarn, let’s look at the cons.


The ball band recommends machine washing and tumble trying, but I would absolutely not put anything made with this yarn in a machine for washing, and definitely not for drying, and I’ll show you why.

I tension my ball winder by passing the yarn through two fingers. This is what came off.

Mighty Stitch is quite loosely spun, meaning it can pill easily with wear. Machine washing and drying only speed up this process. I had some pilling just from moving the sweater around as I worked on it; I can only imagine what it would look like after an hour in the dryer. I have a feeling this sweater will have to be washed sparingly and in the bathtub.

It might hold up better if you knit it at a denser gauge, say with a US4-5 needle, but otherwise I wouldn’t risk it. I wound up my leftovers using my ball winder, and this is what my hand looked like after the fact:

You see all that fuzz? Those are the loose fibers that form pills on your sweaters. This was just from winding up 3/4 of a skein into a ball, not nearly the amount of friction areas like under arms get exposed to during normal wear.


Overall, I do like this yarn. It’s soft, economical, and comes in a range of colors. But, because it’s not very hard wearing, I would save it for things like hats that won’t be exposed to a lot of friction. I’d also recommend hand washing, laying flat to dry, and using a much smaller needle or hook than is recommended on the ball band to try to combat the weakness of the yarn. But will I make another sweater with it? Not a chance.
