This beginner friendly crochet beanie hat is the perfect hat to keep you warm during these colder months. Constructed from the bottom up and worked in rounds using just a one row repeat, this pattern will suit any level of crochet knowledge. If you know how to work basic crochet stitches this pattern is perfect for you.
The beanie comes in a wide range of sizes ranging from newborn all the way up to an adult large so it really is the perfect hat for the entire family. I give details in the pattern if you really want to customise your hat making it the perfect size.

To make the beanie hat we will first create the brim, then crochet in lots of rounds until we reach the desired height for your size. We will then weave our yarn around the top of the hat, pulling the yarn to cinch the top closed. One or two stitches are used to secure the top of the hat and finally we will add our favorite pom pom.
YARN
The yarn I used for this Oisín beanie hat was kindly gifted to me by Yarn Vibes. When they contacted me and asked if I would like to try out their Cliffs of Moher range I immediately said yes. Yarn Vibes is an Irish company and their goal is to produce the finest quality and ethically sourced yarn.

Yarn Vibes recently launched their new range, the Cliffs of Moher yarn. It’s a 100% wool yarn that comes in a range of jewel-tones and marls.

Rep last round until entire height of beanie hat measures 5(6, 6.5, 7.5, 8, 8.5, 9.5, 10) inches. You can add more rounds here for a slouchier look.
Fasten off leaving a long tail (about 10 inches). With your long tail and yarn needle weave in and out of each stitch at the top of the beanie. When you have weaved through each stitch you will next pull your yarn slightly making sure not to pull too hard because the yarn might snap. Pulling the yarn will cinch the top of the beanie closed.
Secure the top of the beanie hat with a couple stitches. Add a faux fur pom pom or make your own pom pom using some yarn and attach to the top of the hat. You are now finished your beanie!
HOW TO MAKE A PERFECT SIZE BEANIE TO FIT YOUR HEAD PERFECTLY USING ANY YARN OR HOOK
Your foundation chain determines the height of the brim so make a chain to your desired height.
Continue as in pattern making rows of slsts working in the back loop only until the brim is long enough to go around your head. Slst the two ends together.
Next ch 1 and make single crochets around the entire brim of the beanie but you MUST work in MULTIPLES OF 5.
Repeat as for the pattern until you are happy with the height of your beanie and fasten off. Cinch the top of the hat using the cinching method described in the above pattern and you are good to go!
