Using just two contrasting colors of worsted weight yarn, you'll create a dense, plush, and modern accessory that resembles a handwoven textile. Let's dive into this free pattern and create your new favorite fall staple!

Materials Needed

Before you begin, gather the following supplies. This project is portable and requires minimal tools, making it perfect for cozy evenings on the couch.

• Yarn: Worsted weight yarn in 2 contrasting colors. You will need approximately 220 yards of Color A and 180 yards of Color B. Suggested: Lion Brand Wool-Ease in 'Mustard' (Color A) and 'Forest Green' (Color B) for that perfect harvest vibe.
• Crochet Hook: Size H/8 (5.0 mm) hook. Adjust hook size if necessary to achieve gauge.
• Notions: Yarn needle for weaving in ends and seaming, and a pair of scissors.
• Gauge: 16 stitches and 12 rows = 4 inches in single crochet. Note: Gauge is not critical for this scarf, but it will affect the final size and drape. A looser gauge creates a drapier scarf.

Pattern Notes & Abbreviations

This infinity scarf is worked flat in rows, then seamed at the short ends to form a continuous loop. The mosaic effect is achieved by working single crochet (sc) and double crochet (dc) stitches in a specific sequence. The unused yarn is carried loosely along the side edge, creating a neat selvedge.

• ch: Chain
• sc: Single Crochet
• dc: Double Crochet
• BLO: Back Loop Only (This is crucial for the mosaic technique to hide the carried yarn).
• st(s): Stitch(es)

Important Technique: When working the single crochet stitches that are placed over the carried yarn (in Rows 4 and 8), you will always work into the Back Loop Only (BLO). This leaves the front loop free and creates the distinctive woven look of mosaic crochet. The double crochet stitches are worked into both loops.

Step-by-Step Instructions

Follow these instructions carefully. The pattern is broken down into a foundation, a 4-row repeat, and finishing. Take your time with the first repeat, and you'll quickly get into a rhythm.

Foundation & First Rows

Foundation Row (Color A): Chain 121 loosely. Single crochet in the 2nd chain from the hook and in each chain across. (120 sc). Turn.

Row 1 (Color A): Chain 1 (does not count as a stitch here and throughout). Single crochet in the first stitch and in each stitch across. (120 sc). Turn. This row establishes a clean base.

Row 2 (Color B): Chain 1. Single crochet in the first stitch. *Skip the next stitch, work 1 double crochet in the next stitch. Repeat from * across, ending with a single crochet in the last stitch. Turn. (You will have 60 sc and 60 dc).

Row 3 (Color B): Chain 1. Single crochet in the first stitch. *Work 1 double crochet in the next stitch (this will be a single crochet from the row below), then skip the next stitch (which is a double crochet from the previous row). Repeat from * across, ending with a single crochet in the last stitch. Turn. (60 sc, 60 dc). This row staggers the double crochets.

Row 4 (Color A): Chain 1. Single crochet in the first stitch. *Work 1 single crochet in the BLO of the next double crochet, then work 1 single crochet in the BLO of the next single crochet (this is the skipped stitch from two rows below). Repeat from * across, ending with a single crochet in the last stitch. Turn. (120 sc). Tip: This row pulls the fabric together and creates the mosaic overlay.

Establishing the Pattern Repeat

Row 5 (Color A): Chain 1. Single crochet in each stitch across. (120 sc). Turn.

Row 6 (Color B): Chain 1. Single crochet in the first stitch. *Work 1 double crochet in the next stitch, skip the next stitch. Repeat from * across, ending with a single crochet in the last stitch. Turn. (60 sc, 60 dc).

Row 7 (Color B): Chain 1. Single crochet in the first stitch. *Skip the next double crochet, work 1 double crochet in the next single crochet. Repeat from * across, ending with a single crochet in the last stitch. Turn. (60 sc, 60 dc).

Row 8 (Color A): Chain 1. Single crochet in the first stitch. *Work 1 single crochet in the BLO of the next double crochet, then work 1 single crochet in the BLO of the next single crochet (the skipped stitch from two rows below). Repeat from * across, ending with a single crochet in the last stitch. Turn. (120 sc).

Continuing the Body

Rows 9-40: Repeat Rows 5-8 eight more times, alternating colors as established. This means you will work Rows 9-12 in Color A, Rows 13-16 in Color B, and so on. You will have a total of 40 rows worked. Remember to carry the unused yarn loosely up the side of the work.

Finishing & Seaming

Final Row (Color A): Chain 1. Single crochet in each stitch across. (120 sc). Fasten off, leaving a long tail (at least 18 inches) for seaming.

Seaming: Fold the scarf in half with right sides together, matching the short ends. Using the yarn needle and the long tail, whip stitch the two ends together securely. Take small, even stitches through the top loops of the stitches on both edges. Fasten off and weave in the tail.

Weave in Ends: Using your yarn needle, carefully weave in all remaining loose ends from your color changes on the wrong side of the fabric.

Finishing: Turn the scarf right side out. Gently steam block the scarf to open up the mosaic pattern and even out the stitches. Lay it flat to dry completely. Your Harvest Mosaic Infinity Scarf is ready to wear!

This pattern is a wonderful way to practice colorwork without the complexity of tapestry crochet. The result is a stunning, professional-looking scarf that will keep you warm and stylish all season long. Happy crocheting!
