Worsted Weight Yarn for Knitting & Crochet

Worsted weight yarn, also known as medium weight yarn or size 4 yarn, is the workhorse of the knitting and crochet world. Slightly thicker than DK weight and lighter than bulky yarn, worsted yarn weight is perfect for a wide range of projects from cozy sweaters and textured hats to afghans, blankets, scarves, and home décor.

Gorgeous selection of yarn, luxury, hand-dyed, novelty, whatever you like! I can rely on the yarn descriptions to be informative and accurate. The prices are wonderful, too. And after I make a selection (hard because I want everything!) I don't have to dream about my next project for very long; my yarn always arrives swiftly and well packaged. I'm a customer for life!

I have always loved the yarn that I have gotten from little knit. I have told several friends to purchase yarn from them. You must buy all that you need as you can not go back and order more of that yarn. Thank you little knit!

Littleknits.com is wonderful. I recommend them all the time. Now with the Tariffs, I get a chance to buy yarn I could afford otherwise. They also give me a chance to try new brands I wasn't familiar with and re purchase. Their discounts are amazing, and the bags of 5 or 10, can give you a sweaters quantity at an affordable price. Many times under $50, when it would be hundreds at full price.
They will call/text you if your order has more than one dye lot. They have cheerful notes on their invoices. Definitely better customer service than I get at my snobby LYS 3 blocks away from my house.

Who doesn't love a sale? Especially from yarns around the world. For as long as LK was in business online (20 years?) I have been a customer ever since. I love their "Customer First" business model, which I appreciate when they act as an eye on the yarn and colors, one thing online shopping is greatly benefitted. For 20 years, I never encounter any mistake or error. Due to their deep discount on yarn, I was able to expend my knitting adventure and exploring my experience in creating my own kind of knitting. I can only wish LK will outlive my hands and eyes, I cannot imaging to knit without LK, since so much changes in the knitting world these days. Does anything good can stay constant? I wonder, but I am busy to go back to my yarn stash from LK purchases to create more, and to enjoy the pure pleasure in playing with those yarns, BIG THANKS to LK.

I love Little Knits! The are local to me and have the most beautiful luxury yarns at bargain prices. Customer service is excellent, and shipping is always prompt! Little Knits is the absolute best and my number one go to for yarn!

Little Knits is my go-to yarn store! I almost never purchase yarn anywhere else unless I need something specific that they don't carry but that is rare. Usually if I decide on a project I peruse what Little Knits has to offer and almost always find something that will work just great, and it's always at a better price than anywhere else. I have the advantage of living nearby so I can always pick up my order and interact with the very fun staff there, but they do offer free shipping on many of their specials for those not so fortunate. Pattern support is often available for free or at a significant discount. I can't say enough great things about this business and their commitment to finding the best yarn offerings at amazing prices!

I just want to tell you how great Araucania Huasco Chunky Kettle Dyes yarn is. I have made hats, scarfs, fingerless mittens and I am designing a handbag on my own. I love working with this yarn it is awesome and looks great.

I enjoy the variety of yarns. Something new every week. Reliable colors and descriptions. If a skein doesn't match the others, it is listed separately. Because I don't pay for expedited shipping it takes a while before I can start my new project. They call me if something doesn't seem right. I'm very happy with my yarn and their service.
