The Stitch Behind the Texture
The modern granny stitch is the star of this beanie, creating the beautiful unisex, textured detail around the body of the hat. If you’re new to this stitch, don’t worry! I’ve got you covered with a step-by-step blog post featuring photo tutorials, plus video tutorials for both left- and right-handed crocheters. This stitch works up quickly and adds just the right amount of visual interest without being overly complicated.

Choosing the Right Yarn
This beanie is designed using #4 weight yarn, which makes it warm yet lightweight. For my versions, I used Paintbox Simply Aran, a soft and durable 100% acrylic yarn that holds up beautifully over time. But don’t worry if you have a different worsted-weight yarn in your stash—this pattern is versatile and works well with any #4 weight yarn.
Here’s what you’ll need:
- Yardage: 55 – 190 yards, depending on the size
- Fiber Options: Acrylic, wool, cotton, or blends—just be careful with wool as it can cause allergies.
- Recommended Hook Size: 5mm (H) crochet hook (adjust as needed for gauge)
Why You’ll Love This Beanie
✔ Unisex Design: Perfect for everyone in the family!
✔ Quick to Crochet: The stitch pattern works up fast, making it a great last-minute gift.
✔ Top-Down Construction: No seaming required—just keep crocheting in rounds!
✔ Customizable: Looks amazing in solid colors, stripes, or even a gradient effect.
✔ Cozy & Warm: The solid crown ensures warmth, while the front post/back post ribbing adds a snug fit around the brim.

Pattern Notes:
- Written in US Terms
- CH1 or CH2 stitches at the beginning of each round do not count as a st unless otherwise stated.
- Ch2 stitches between the DC3Tog do count as stitches.
- The stitch count remains the same for each row. They are given at the end of each row up to round 13 when each round maintains the same stitch count.
- Where the stitch count is the same for each size only one count will be given.
- The stitch multiple to adjust this pattern if required is 3.
- If you cannot meet gauge this pattern will still work. Work the crown until you reach the correct diameter for the size you are making. If you are just below the size required and another round of HDC will make the crown too big, work round 13 to get it to the correct size.
- Where pattern is different per size this will be shown as newborn/6mth/12mths/1-3 yrs/4-10 yrs/ teen/ adult med/adult large.
- Please read the pattern and ensure you are comfortable with it before starting your project.
- When measuring the length of your hat when working the main body, you do so from the top of the crown.
- You may end on any row before starting the brim.
