This pattern is perfect for adventurous beginners who want to try the mosaic crochet technique—a simple method that creates the illusion of intricate colorwork by working with one color per row and carrying the others up the side. The result is a beautifully textured fabric with raised stitches that feels as luxurious as it looks.

Materials Needed

Before you begin, gather the following supplies. This project uses worsted weight cotton yarn, which is ideal for placemats because it's durable, absorbent, and holds its shape well through repeated washing.

Finished Size: Each placemat measures approximately 14 x 18 inches. The pattern makes one placemat; repeat for a full set.

Understanding Mosaic Crochet

Mosaic crochet is a colorwork technique where you work with one color at a time, creating patterns by making double crochet stitches that "float" over the previous row's color. The unused yarn is carried up the side of your work, creating a neat selvedge edge. This technique is easier than it looks—you'll only ever work with one strand at a time, and the pattern is created by alternating single crochet and double crochet stitches.

Key terms:

• sc = single crochet
• dc = double crochet
• ch = chain
• st(s) = stitch(es)
• RS = right side
• WS = wrong side

Step-by-Step Instructions

Follow these detailed instructions carefully. The pattern is worked in rows, and each mosaic row is followed by a solid row in the same color to create the geometric effect. The placemat is worked from the bottom up.

Foundation

With Color A (Cream), chain 45.

Row 1 (Right Side)

Single crochet in the 2nd chain from the hook and in each chain across. Turn. (You should have 44 single crochet stitches.)

Row 2 (Wrong Side)

Chain 1, single crochet in each stitch across. Turn. (44 sc)

Row 3 (Mosaic Row – Color B)

With Color B (Burnt Orange), chain 1, single crochet in the first stitch. Then, *double crochet in the next stitch (working over the Color A strand from the previous rows), single crochet in the next stitch*. Repeat from * to * across the row, ending with a single crochet in the last stitch. Turn.

Tip: When making the double crochet stitches, insert your hook into the stitch as normal, but make sure the carried Color A strand is behind your work. This creates the raised mosaic effect.

Row 4 (Solid Row – Color B)

With Color B, chain 1, single crochet in each stitch across. Turn. (44 sc)

Row 5 (Mosaic Row – Color A)

With Color A, chain 1, single crochet in the first 2 stitches. Then, *double crochet in the next stitch (working over the Color B strand), single crochet in the next stitch*. Repeat from * to * across, ending with single crochet in the last 2 stitches. Turn.

Note: This row is offset by one stitch compared to Row 3, which creates the diagonal zigzag effect.

Row 6 (Solid Row – Color A)

With Color A, chain 1, single crochet in each stitch across. Turn. (44 sc)

Row 7 (Mosaic Row – Color C)

With Color C (Deep Teal), chain 1, single crochet in the first stitch. Then, *double crochet in the next stitch, single crochet in the next stitch*. Repeat from * to * across the row, ending with a single crochet in the last stitch. Turn.

Row 8 (Solid Row – Color C)

With Color C, chain 1, single crochet in each stitch across. Turn. (44 sc)

Repeat the Pattern

Repeat Rows 3–8, alternating between Color B and Color C for the mosaic rows (i.e., Row 3 with B, Row 5 with A, Row 7 with C, then repeat with B, A, C, and so on). Continue until the piece measures approximately 17 inches from the foundation chain. Important: End with a solid row (Row 4, 6, or 8) to ensure a clean edge.

Final Border

With Color A (Cream), chain 1. Single crochet evenly around all four edges of the placemat, working 3 single crochet stitches in each corner to turn the corner smoothly. When you reach the starting point, join with a slip stitch to the first single crochet. Fasten off.

Border tip: Work approximately 1 single crochet per row along the sides and 1 single crochet per stitch along the top and bottom edges. The 3-sc corners will help the border lie flat.

Finishing

Weave in all loose ends using a yarn needle. Be sure to secure the carried yarn strands at the sides of your work by weaving them into the border stitches. Gently block the placemat if desired to even out the stitches and ensure it lies flat.

Repeat for a Second Placemat

This pattern makes one placemat. For a complete table setting, repeat the entire process to create a second (or more) placemat. The color sequence will naturally alternate, so if you want all placemats to look identical, start each one with the same color sequence.

Tips for Success

• Keep tension consistent: Mosaic crochet looks best when your tension is even. Practice on a small swatch first if you're new to the technique.
• Carry yarn loosely: When carrying the unused color up the side, don't pull it too tight—this will cause the edges to curl. Leave a little slack.
• Count your stitches: Each row should have exactly 44 stitches. If you find yourself off by one, check your work before continuing.
• Use stitch markers: Place a marker at the beginning of each row to help you keep track of your place, especially when repeating the pattern.

These Harvest Moon Mosaic Crochet Placemats are a beautiful way to celebrate the season. The combination of warm burnt orange, deep teal, and cream creates a palette that evokes autumn leaves and twilight skies, while the textured geometric pattern adds depth and interest to your table. Whether you're a seasoned crocheter or trying mosaic crochet for the first time, this pattern is sure to become a favorite fall project. Happy crocheting!
