Mosaic Ridge Adult Crochet Pullover

Fall in love with the Mosaic Ridge Adult Crochet Pullover! This stunning piece is worked in the round, using a top-down yoke style that makes for a seamless and cozy fit.

What is Overlay Mosaic Crochet?

Overlay Mosaic Crochet is a colorwork technique that creates intricate patterns by layering contrasting colors over each other.

In this technique, geometric designs and motifs are crocheted by working stitches over rows of different colors, allowing for bold and visually striking patterns without the need for complex color changes in every stitch. We will only work one strand of yarn at a time, no need to be switching back and forth in a round to do the color work.

Basic Technique: Overlay mosaic crochet uses single crochet and double crochet stitches, usually worked in the back loops only. To create the overlay effect, double crochet stitches are placed two rows below the current working row, crossing over the front of the fabric.

Each row is worked with just one color, and colors are switched at the end of the row to maintain the pattern. The unused yarn is carried up the sides, keeping the project neat and reducing the number of ends to weave in. This technique allows for beautiful colorwork with less hassle, making it accessible for various skill levels.

Construction

This crochet sweater is constructed using a top-down, circular yoke design. We begin by working the neck ribbing in rows, which are then joined to continue in rounds. The overlay mosaic yoke is crafted with simple increases to shape the shoulders. After completing the yoke, we'll separate the stitches for the sleeves and body. The body is crocheted down to the bottom ribbing, and the sleeves are worked separately, finishing with a cuff for a polished look. The Pine Fair Isle Sweater and the Fawning Over You Sweater are constructed in a similar fashion!

Special Stitches

Mosaic Double Crochet (mdc): is worked as a double crochet stitch, but it will be worked into the skipped stitch three rows below. This stitch will be worked on the front (or right sides) of the cardigan.

Extended half double crochet (Ehdc): is a variation of the half double crochet (Hdc) that adds a bit more height and drape to the stitch. Start by yarn over (YO) and insert your hook into the stitch, YO again and pull through the stitch (3 loops on your hook). YO and pull through the first loop on your hook only (3 loops on your hook). YO once more and pull through all three loops to complete the extended half double crochet.

Extended half double crochet 2 together (Ehdc2tog): yarn over (YO) and insert your hook into the stitch, YO again and pull through the stitch (3 loops on your hook), (YO) and insert your hook into the next stitch, YO again and pull through the stitch (4 loops on your hook). YO and pull through 2 loops on your hook only (3 loops on your hook). YO once more and pull through all three loops to complete the Ehdc2tog.

Style

Casual Look: Pair the sweater with high-waisted jeans and ankle boots. The intricate mosaic design adds texture and interest, making it the standout piece of the outfit. Add a Herringbone Clutch in a coordinating color to complete your look.

Layered: Wear a collared shirt underneath, letting the collar and cuffs peek out for a preppy, layered style. Opt for neutral shades to complement the sweater's colorwork. The Just a Rectangle Bag would look gorgeous in a warm or cool solid and would complement your sweater perfectly!

Sporty: For a laid-back, sporty feel, pair the sweater with leggings and sneakers. On a chilly day, add a simple hat, like the Extend That Mellow Beanie, to keep warm and cozy.

Customization Tips

Want a cropped sweater? Simply work fewer rounds of the body to adjust the length. And you could even keep on going and turn this into a sweater dress!

You can easily adjust the sleeve length before starting the cuff—just add or reduce the number of rows to reach your desired length. For a puff sleeve effect, skip the decreases but keep the same number of cuff rows around the bottom of the sleeve.

Sleeves

Rnd 1:

Join the yarn to the center of the underarm, sc in first (place marker), Ehdc in next, Ehdc in remaining sts around the arm opening, do not join and work continuously. Tip: Be careful not to miss any stitches or pick up any extras; check your stitch count. There will be a gap on each underarm side, use your tail end to close these gaps, see video for tip. | 62 (63, 64, 66, 67) (67, 71, 72, 72) sts

The sleeve rounds will be decreased to the cuff. You can adjust as needed for your fit, add or reduce the number of rnds for a custom sleeve length.

Tip: To avoid a 'wandering decrease,' try keeping the decrease under the center arm but mixing up the placement every few rounds.

Heck yeah!

Weave in any ends, block the garment if needed, and enjoy!

The great thing about colorwork designs is that you can mix up the tones to create something that expresses your unique style. Use contrasting solid colors for a bold, eye-catching look.

Alternatively, you can use a single color with varying shades—either lighter or darker—for a subtle mosaic effect. You can also switch up the main and accent colors: try working the body in the color-changing Prism yarn while the mosaic colorwork is done in a solid Mellowspun.

The choice is yours - and it’s going to be gorgeous no matter what you choose! If you loved making a mosaic sweater, you might also love making a Lotus Blanket or a Waves Blanket!

Cheers, and happy crocheting!
