Bernat All-In-One Blanket Yarn Granny Square Trees Guide
These fuzzy, geometric tree motifs feel like holding a soft cloud thanks to the self-striping weight of the blanket yarn. Using the clever print placement of the Bernat yarn, you create a complete color-blocked tree in just a few rounds of basic double crochet. This project suits beginners who want to practice joining squares without the usual frustration of switching colors manually. You will enjoy how the yarn does the heavy lifting, shifting naturally from bark brown to deep evergreen shades as you work. The final square lays flat and dense, creating a sturdy base for festive home decor projects or a cozy seasonal gift.

Why You’ll Love This Pattern
This crochet ribbed beanie pattern utilizes a simple back-loop-only technique that creates a professional, store-bought look with minimal effort. You work the entire hat as a flat rectangle, which simplifies the process for beginners who may struggle with circular increases or complex counting. Because the ribbed fabric is naturally stretchy, it accommodates a wide range of head sizes without needing complicated gauge adjustments. You can complete this project in a single afternoon, making it a perfect choice for last-minute gifts or stash-busting your collection of worsted-weight yarn.
I finally finished my first hat using this pattern and the ribbing looks so clean. It took me much less time than I expected and fits perfectly.

Step-by-Step Pattern Instructions
Hat Body
The hat is worked in rows to create a ribbed texture. The height of the rectangle determines how much of a fold-over brim you have.
- Row 1: Ch 41. Sc in second ch from hook and each ch across. (40 sts)
- Row 2: Ch 1, turn. Sc in BLO of each st across. (40 sts)
- Rows 3-60: Repeat Row 2 until the piece measures approximately 18 inches when slightly stretched. Do not fasten off after the final row. (40 sts)
Assembly and Finishing
- Fold the rectangle in half so the short ends meet.
- Slip stitch through the back loop of the last row and the starting chain edge to create a tube. Fasten off, leaving a 12-inch long yarn tail.
- Thread the tail onto a tapestry needle. Weave the yarn in and out along one of the open edges of the tube.
- Pull the yarn tight to cinch the opening closed. Secure the knot firmly.
- Weave in all loose ends on the inside of the hat to keep the exterior neat.
Care & Washing Instructions
- Hand wash in cool water using a mild detergent to preserve the fibers.
- Lay the hat flat on a clean towel to air dry; avoid hanging, which can stretch the fabric out of shape.
- Do not iron or bleach, as these can permanently damage the texture of the stitches.
Pro Tips & Common Mistakes to Avoid
Maintain consistent tension throughout the project, as changes in tightness will cause the ribbed fabric to ripple or pucker. Use a stitch marker on the first stitch of every row to ensure you do not accidentally drop stitches at the edges, which would result in a slanted top. When weaving in ends, follow the path of the stitches on the inside of the work to ensure the tails remain hidden and secure. To adjust the size, simply add or subtract chains at the beginning; each 2 chains add roughly 1 inch of length to the hat height.
Frequently Asked Questions
Can I use a thicker yarn for this pattern?
Yes, you can use a chunky #5 weight yarn, but you will need to adjust your hook size to match the yarn label and reduce the number of starting chains, as the fabric will be significantly thicker and wider.
Is this project suitable for a complete beginner?
Absolutely, because this pattern uses only single crochet stitches and works in rows, it is a great way to practice basic control and tension without worrying about complex shaping.
How do I resize this for a child?
Decrease the number of starting chains to roughly 30 or 35 depending on the child’s head size, and stop working the rows once the piece wraps comfortably around their head.
Am I allowed to sell hats made from this pattern?
You are welcome to sell finished items created from this pattern, provided you credit the design, but you may not distribute or sell the pattern instructions themselves.
