Boston Earwarmer Free Crochet Pattern

Boston Earwarmer Crochet Pattern

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! 

Pattern Details

The Boston Earwarmer is made with sport (#2) or dk(#3) weight yarn. I used a gorgeous hand dyed dk weight yarn from KT and the Squid yarns.

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.

  2. 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?
