Countless of you have reached out wondering about other tiny makes to crochet for babies.

Enter this sweet little crochet preemie hat.  There is so much to love about this little beauty for baby.  First up.. it uses very little yarn (just 3/8 of an ounce).  So this free crochet pattern is perfect for all those worsted weight scraps you have in your yarn stash.

Most of the hat is worked in half double crochet stitch in the round, so it is easy, fast crocheting.  It is the perfect binge while you watch TV project. The brim is where all the magic happens.  I wanted a tiny ribbed edge and it was tricky to find a stitch combination that gave me both the functionality and look I wanted.

Enter a row of post stitches in half double crochet and another in single crochet.  Preemie baby hat perfection!  Of course, if you don’t want to crochet ribbing, you can just continue rounds of half double crochet until you reach the total height of the crochet hat too.  You can also attach a tiny pom pom to the top, if you’d like. A tiny baby just wants to be warm, after all!

  1. I found a free preemie hat pattern that I want to use but I can’t figure out how to print it. When I click on the “print free pattern” it ask me to sign up which I did but still doesn’t allow me to print it. What am I missing?

    1. There is a free printable version of the Preemie Hat in my resource library, which is a perk of being an email subscriber. Just check your inbox for the latest email from me and everything you need to get in the library will be there!
