After writing an article about scarves and shawls, I thought it would be nice to offer you the matching hat option.
To do this, I chose to present the YO hat by Ivanne S. for three reasons:
- It offers two models: a classic one and a more streetwear style.
- The pattern includes a child version and an adult version, something to please the whole family.
- The tutorial gathers quite a few tips and tricks (height modification, two-tone version...) as well as upcycling advice.
Let's go, let's discover this pattern together!

Where to find the pattern?
You will find the YO hat pattern on Ivanne S.'s website, a pattern designer who offers books and patterns.
You can download the hat pattern in PDF for 3.5 euros. Click here to find it.
The pattern is to be printed on A4, it's very easy to assemble. Each model (version 1 and 2 as well as the child and adult versions) fits on 4 pages that just need to be put together following the markers.
Attention, seam allowances are not included. You will need to add them when cutting!

Who is the pattern for?
For children, two sizes are offered depending on head circumference:
- between 45 and 49cm
- between 50 and 53cm
For adults, the two sizes are:
- between 54 and 58cm
- between 59 and 63cm
Who can sew the YO hat?
Everyone! If you are a beginner and want to start sewing stretch fabrics, this is a good project to begin with.

To sew the YO hat, you will need stretch material, so knit fabrics like jersey, tubular ribbing, ... but also knits like an old sweater could work. The important thing is to have good fabric stretch and softness to the touch.
For the yardage, if you choose the solid color version, you will need a fabric coupon between 45X55cm (smallest child size) and 60X70cm (largest adult size). So it's also a great project for using up knit fabric scraps.
- stretch fabric, either a single piece or two for the reversible version (or for a contrasting cuff). You’ll find beautiful knits and tubular ribbing in the shop to make your hat.
- thread
- a sewing machine
- a machine needle designed for stretch or jersey
What should you pay attention to when sewing the hat?
The usual precautions always apply: pre-washing, careful cutting of the pattern and fabric...
Be sure to add seam allowances as they are not included. For my part, I chose to add a 0.7cm allowance to avoid creating too much bulk at the assembly seams.
Special attention should be given to assembling the tip of the hat to create neat joins and avoid "points" at the corners as much as possible. To do this, you’ll need to "clip" the seams on the sides to avoid leaving raw corners. Notching is also possible to prevent tension in these seams.
To make a nice match at the top of the hat, be sure to carefully "align" the seams when pinning.
Another point to watch is to leave an opening to turn the piece inside out when assembling the large side seam. My little trick to remember to stop is to always place glass-headed pins to mark both sides of the opening. It’s my little reminder when sewing—when I come across them, I remember to stop! You can find them for sale in the shop.
Finally, you’ll need to close this opening with a few invisible hand stitches. And ta-da, your first hat is finished! You can make more for the whole family and/or friends in solid or two-tone versions.
For my godson, I made a rabbit hat matching his scarf and another two-tone one that will match the two joggers I made him as a Christmas gift. He's going to be stylish, all coordinated like that ;-)
And for those who want to take it a step further, why not add a pompom? It's a fun project to do with a child for a sewing project in pairs.
Can't wait to see your beautiful creations and your scarf/hat duos ;-)
Get your needles ready!
