Knit Diamond Mosaic Cushion Cover in Bernat Blanket – Pattern Summary

This intermediate-level knitting pattern from the Bernat Design Team produces a striking 24-inch square cushion cover featuring a bold diamond mosaic design. The pattern is available as a free downloadable PDF and is an excellent project for knitters who are comfortable with basic techniques and ready to explore the satisfying world of mosaic colorwork.

What Is Being Made

The finished project is a cushion cover measuring approximately 24" [61 cm] square, designed to fit a standard 24-inch square pillow form. The cover features a geometric diamond motif created through mosaic knitting, a technique that produces intricate, multi-color patterns while working with only one color at a time per row. A single button closure completes the practical construction.

Design and Colorwork Details

The visual impact of this cushion cover comes from a carefully sequenced use of three contrasting colors of Bernat Blanket yarn. The pattern instructs knitters to work three full repeats of a 40-row chart, rotating the color assignments across each repeat:

• First repeat: Contrast A Coal (10040) as Color 1 and Contrast B Vintage White (10006) as Color 2
• Second repeat: Contrast C Malachite (10802) as Color 1 and Contrast B Vintage White (10006) as Color 2
• Third repeat: Contrast A Coal (10040) as Color 1 and Contrast B Vintage White (10006) as Color 2

This rotation of deep charcoal, rich teal-green, and crisp white creates a dynamic, layered look across the front panel of the cushion cover. Vintage White serves as the consistent contrast color throughout, anchoring the design and unifying the three sections.

Techniques Used

Mosaic knitting is the defining technique of this pattern. Unlike traditional stranded colorwork, mosaic knitting uses only one color per row — the second color is introduced by slipping stitches from the previous row rather than carrying yarn across the back. This makes it significantly more approachable than Fair Isle or intarsia while still producing complex-looking results. Key technique details include:

• Working from a two-color chart, reading right-side rows from right to left and wrong-side rows from left to right
• On right-side rows, contrast color stitches are slipped purlwise with yarn held at the back (Sl1Pwyib)
• On wrong-side rows, contrast color stitches are slipped purlwise with yarn held at the front (Sl1Pwyif)
• The working color on wrong-side rows always matches the color used on the previous right-side row, maintaining clean color separation
• A foundation row is purled on the wrong side before beginning the chart

This slip-stitch approach means that even though the finished fabric looks like it involves complex color manipulation, knitters only ever manage one strand of yarn at a time — a major advantage when working with a thick, textured yarn like Bernat Blanket.

Stitches Used

• Knit stitch – used on all right-side chart rows
• Purl stitch – used on all wrong-side chart rows and the initial foundation row
• Sl1Pwyib – slip one stitch purlwise with yarn at back, used on right-side rows to carry contrast color stitches
• Sl1Pwyif – slip one stitch purlwise with yarn at front, used on wrong-side rows to carry contrast color stitches
• Cast on – 54 stitches are cast on to begin the front panel

Materials

The pattern calls for Bernat Blanket yarn, a super chunky (size 6) weight yarn known for its exceptionally soft, chen
