The Frosted Berry Mosaic Throw is more than just a blanket—it's a statement piece.

Why You'll Love This Pattern

This pattern is perfect for knitters who want to create something truly special. The mosaic technique uses only knit and purl stitches with slipped stitches, making it accessible even if you've never tried mosaic knitting before. The two-row color stripes create the illusion of complex Fair Isle work without the hassle of carrying multiple yarns across rows. Plus, the finished throw makes an incredible handmade gift for weddings, housewarmings, or holiday celebrations.

Materials Needed

Before you begin, gather all your materials to ensure a smooth knitting experience. Here's everything you'll need:

Yarn

• Color A (Deep Burgundy): 1200g worsted weight yarn
• Color B (Forest Green): 900g worsted weight yarn
• Color C (Cream): 600g worsted weight yarn

Suggested yarn: Lion Brand Wool-Ease Worsted or any comparable worsted weight yarn that achieves the recommended gauge.

Needles & Notions

• US 8 (5mm) circular knitting needle, 40-inch length (or size needed to obtain gauge)
• Stitch markers (optional, for tracking pattern repeats)
• Tapestry needle for weaving in ends
• Blocking mats and pins

Gauge

18 stitches and 24 rows = 4 inches in stockinette stitch (blocked)

Always take time to swatch and block your gauge sample before starting. This ensures your finished throw will measure approximately 50 inches wide by 60 inches long as designed.

Understanding Mosaic Knitting

Mosaic knitting is a colorwork technique that uses slipped stitches to create patterns. You work with only one color at a time, alternating between two colors every two rows. The key is that on the first row of each color, you knit or purl certain stitches and slip others. On the second row (the return row), you slip the same stitches you slipped before, but with the yarn held in front. This creates vertical columns of color that form the pattern.

For this pattern, you'll be working with three colors, but only two at a time. The main body alternates between Color A and Color B, with Color C used for the garter stripes between pattern repeats. This creates a beautiful layered effect that mimics a winterberry tapestry.

Step-by-Step Instructions

Abbreviations

• K = knit
• P = purl
• Sl = slip stitch purlwise with yarn in back (unless noted)
• Yo = yarn over
• K2tog = knit two together
• Rep = repeat
• St(s) = stitch(es)
• RS = right side
• WS = wrong side

Pattern Notes

• The throw measures approximately 50 inches wide by 60 inches long.
• Work all slipped stitches on RS rows with yarn in back; on WS rows, slip with yarn in front.
• The mosaic pattern is created by working two-row stripes in one color while slipping stitches from the previous color, forming the design.
• Read all instructions carefully before beginning.

Cast On

With Color A, cast on 225 stitches loosely. A long-tail cast on works beautifully here, but any stretchy cast on method will do. Take your time to ensure your cast on edge is even and not too tight, as this will affect the drape of your finished throw.

Border (Worked in Color A)

Rows 1-8: Knit all stitches (garter stitch border). This creates a clean, sturdy edge that will frame your mosaic pattern beautifully.

Main Body

The body is composed of 12 repeats of the 40-row mosaic pattern, separated by 4-row garter stripes in Color B. Each repeat adds approximately 5 inches to the length of your throw, so you can easily adjust the final size by adding or removing repeats.

Garter Stripe Between Repeats

After completing Row 40, work 4 rows of garter stitch in Color B (knit every row). This creates a beautiful textural break between the mosaic patterns and adds visual interest to the overall design.

Repeating the Pattern

Repeat the 40-row mosaic pattern and the 4-row garter stripe a total of 12 times, or until the throw reaches your desired length, ending with a garter stripe in Color B. Each full repeat (44 rows) adds approximately 7 inches to your throw, so you can easily customize the final size.

Finishing Border

Switch to Color A and knit 8 rows of garter stitch for the bottom border. This mirrors the top border and creates a balanced, professional
