I just love a simple crochet earwarmer that I can throw on when I need to keep my ears warm! The Boston Earwarmer is simple, worked in the round, and has lots of stretchy texture! I love to make this one in all my favorite color yarns and have one for every outfit!

This crochet earwarmer project is super quick and will only take an hour or so to make! This makes it a great project for gifts or selling at market or online!
Pattern Details
The Yarn
The Boston Earwarmer is made with DK (#3) weight yarn. I used one of my favorite DK yarns ever, Swish DK from WeCrochet! Swish DK is 100% superwash merino wool and is so soft and warm! Check out my full review on my YouTube Channel! I used the colorway Marina for the earwarmer pictured in this post.
It is all worked in the round, no buttons or sewing to attach it.
The pattern comes with instructions for sizes toddler, children’s, small adult, and large adult.
The pattern is rated Easy in difficulty. You will need to know the Chainless Foundation Single Crochet stitch and the basic crochet stitches.

Love it making some Ear Warmers for Christmas presents for a friend of mine who I will see next week. So Perfect timing. Thank you for sharing this pattern.
I have a question. When you finish round 3 and do your turn which stitch do you put your combo stitch into? A single, the hd or do you do it in between the combo?
You’ll put it into an sc.
