Bernat All-In-One Blanket Yarn Granny Square Tree Pattern
These soft holiday trees work up quickly using self-striping blanket yarn that does the color changing for you. The plush, thick texture feels cozy against your skin, making these pieces a favorite for seasonal home decor or handmade gifts that actually get used. Even if you are just starting out with a hook, you will find this construction friendly and rewarding because it relies on basic granny square techniques that grow into a triangle shape quite naturally. You will learn how to transition from a classic square base into a pointed top using simple decreases that maintain the stitch count.
Why You’ll Love This Pattern
This crochet ribbed beanie pattern utilizes a simple rectangular construction that eliminates the need for complex crown shaping or increases. By working in back loops only, you create a natural elasticity that allows the fabric to stretch comfortably while maintaining its shape over time. It serves as an excellent project for utilizing leftover yarn from previous makes, as the stitch pattern remains consistent regardless of color changes. Because the body is worked as a single piece, you only need to master the foundation chain and the single crochet stitch to produce a professional-looking winter accessory.
I finished this hat in two sittings and the fit is perfect because the ribbing pulls in snugly without being tight. This is definitely my new go-to pattern for last-minute gifts.

Pattern Overview & Skill Level
- Skill Level: Beginner
- Approximate Time: 3 to 4 hours
- Construction: Flat rectangle seamed into a tube with a gathered top
- Finished Dimensions & Sizing: Adult medium, approximately 9 inches tall and 18 inches in circumference before stretching
Materials & Supplies Needed
- Yarn: Worsted weight (#4), wool or acrylic blend, approximately 200 yards. Solid colors show the ribbing texture best.
- Hook Size: 5.0 mm (H-8) crochet hook.
- Notions: Yarn needle for seaming, scissors, and a measuring tape.
- Safe yarn substitutions: You can use a DK weight yarn for a lighter feel, though you will need to increase your starting chain length by 2 inches to maintain the same adult sizing. Avoid cotton yarns for this project, as they lack the necessary memory to hold the ribbed shape and may become baggy.
Stitch Guide & Abbreviations (US Terms)
- ch: chain
- sc: single crochet
- st/sts: stitch/stitches
- BLO: back loop only (insert hook under the back loop of the V-shape at the top of the stitch rather than both loops)

Step-by-Step Pattern Instructions
Main Body Panel
Work back and forth in rows. The turning chain does not count as a stitch.
- Row 1: Ch 45. Sc in the second ch from the hook and in each ch across. (44 sts).
- Row 2: Ch 1, turn. Sc in BLO of each st across. (44 sts).
- Rows 3–60: Repeat Row 2 until the piece measures approximately 18 inches wide when laid flat.
- Finishing the panel: FO, leaving a long 15-inch tail for sewing the seam.
Assembly and Shaping
Fold the rectangle in half by bringing the two shorter ends together. Using your yarn needle and the long tail, sl st or whipstitch the two edges together to form a tube. Turn the tube inside out so the seam is on the interior. Thread your yarn needle with a new piece of yarn and weave it in and out along one of the open ends of the tube. Pull the yarn tail tight to gather the top of the hat closed, securing the center with a knot. Weave in all remaining ends to prevent the hat from unraveling during use.
Care & Washing Instructions
- Hand wash in cool water using a mild wool-safe detergent.
- Lay the item flat on a towel to air dry, avoiding direct heat sources that can damage synthetic fibers.
- Reshape the hat gently while damp to ensure the ribbing remains even and the brim stays flat.
Pro Tips & Common Mistakes to Avoid
Maintain consistent tension throughout every row; if your stitches are too tight, the fabric will lose its signature stretchiness. Always count your stitches at the end of every row to ensure you have exactly 44; dropping a stitch will cause the edges of your rectangle to taper, making the final seam uneven. When seaming, use the mattress stitch for a flatter finish that does not create a thick, irritating ridge on the inside of the hat. If you wish to adjust the size, add or subtract chains in multiples of two; adding 4 chains will increase the length of the hat, while adding chains to the row count will increase the circumference.
Frequently Asked Questions
Can I use a chunky yarn for this pattern?
Yes, but you must adjust your hook size to match the yarn label and reduce the starting chain count to about 30 stitches to maintain a standard adult fit.
Is this pattern suitable for someone who has never held a hook?
Yes, because it only uses the single crochet stitch and works in flat rows, which are the fundamental building blocks of crochet.
Can I sell the hats I make from this design?
You are welcome to sell your finished products, but please credit this pattern as the source to support the designer.
How do I know if my tension is correct?
Your fabric should feel squishy and spring back when stretched; if it feels stiff or board-like, try using a hook size 0.5 mm larger than recommended.
Seeing your handmade trees standing on a mantle or bookshelf brings a real sense of accomplishment to the room. You can try these in monochromatic grey or white yarn for a modern, frosty forest look that lasts all winter long. Please share a photo of your finished work on Instagram or Pinterest so other makers can see your color choices. I enjoy seeing how each tree turns out uniquely.
