WHY YOU WILL LOVE THE PROJECT
This project is creative enough but not complicated. You get to have fun making granny squares and then turning them into a finished hat that you can actually wear or give away.
WHAT YOU NEED: SUPPLIES
- String
- Hook for crochet
- Scissors
- Yarn needle
Choose a yarn and hook size to get the fit and feel you want.
YARN FOR THIS PROJECT
Great granny square hat in a soft yarn with good stitch definition. A medium weight yarn is often a good choice for a cosy hat because it gives the squares enough shape without feeling too heavy.
LEVEL OF SKILL
Beginner friendly. The chosen tutorial is called “A detailed step-by-step granny square beanie tutorial for beginners”.
SIZE GUIDE
You can make the fit smaller or larger, by making the squares to the size shown in the tutorial and checking the overall hat shape as you join up. You can always change the yarn, hook or overall join to make it looser or more fitted if desired.
STITCHES PUT ON
This tutorial is based on granny squares, so you can tell it’s using classic granny-style crochet techniques. Watch the video carefully for the exact stitch sequence for the squares and finishing.
HOW TO DO SO

Launch Foundation
First, crochet the granny squares that will form the main body of the hat. Spend some time on the first square to make sure you are happy with the size and tension.
Working the Main Part
Keep making the number of squares shown in the tutorial and keep them as even as possible. I used matching tension to pull the hat together neatly.
Join or Make
When the squares are ready join them together in the arrangement shown so they begin to form the hat shape. Now here’s the good part, where the granny squares turn into something you can wear.
Adjust Size
Try it on as you go. If needed, adjust the finishing section until the hat fits comfortably and sits as you like.
Finish the Edges
Finish the top edge or brim neatly and weave in all the ends carefully so the hat looks nice and polished.
SOME HANDY TIPS
- Make sure all your granny squares are the same size before joining.
- If you don’t want ends piling up at the end, weave in ends as you go.
- If your hat seems too stiff or too loose, changing the hook size can help with the final look.
COMMON MISTAKES YOU SHOULD AVOID
- The size of each Granny Square varies
- Putting pieces together in the wrong order
- Crocheting too tight
- Dont check fit as you go & forget
- Ends left open
IDEAS FOR CUSTOMISATION
Pick bright colours for a playful hat, or soft neutrals for something more classic. Or you could add a pom-pom, change the border colour or mix scrap yarn shades for a fun patchwork look.
STYLE CONCEPTS
Wear this hat with casual wear, cosy cardigans, denim jackets and your everyday winter essentials. Makes a lovely handmade gift too.
CARE INSTRUCTIONS
Wash in cold water, reshape and dry flat. Lay flat to dry to help hat retain its shape.
TIME REQUIRED
This can take a few hours, depending on how fast you knit, your yarn, size and stitch pattern.
