The pattern is available as a downloadable PDF and is rated Easy, making it an excellent choice for beginner and intermediate knitters alike.

What Is Being Made

This pattern creates a knitted throw pillow cover measuring approximately 20 inches [51 cm] square. The cover is worked as a single flat rectangle, then folded in half with the wrong sides facing each other. Two sides are seamed, a standard 20-inch square pillow form is inserted, and the final side is sewn closed. The result is a plump, professional-looking cushion with a richly textured front and back surface.

Colorways and Design Options

The pattern offers three colorway options, all using Caron One Pound yarn:

• Dark Grey Mix (10618) – a deep, sophisticated heathered grey
• Medium Grey Mix (10617) – a lighter, versatile neutral heathered tone
• Sunflower (10549) – a warm, cheerful yellow for a bold pop of color

Each colorway showcases the Trinity Stitch texture beautifully, as the raised pebble clusters catch light differently depending on the shade chosen. All three options are achievable with a single ball of yarn.

Techniques Used

The primary technique in this pattern is flat knitting, meaning the fabric is worked back and forth in rows on straight needles rather than in the round. The construction method is straightforward: knit one long rectangle, fold it, and seam it around a pillow form. This approach is particularly beginner-friendly because there is no shaping, no increases or decreases for fit, and no complex construction to follow.

The finishing technique involves simple mattress stitch or whipstitch seaming along two sides before inserting the pillow form, then closing the final edge. This is a practical and clean method for constructing pillow covers that allows easy removal of the form if needed.

Stitches Used

The entire pillow is worked in the Trinity Stitch pattern, a classic four-row repeating texture stitch that creates dense, rounded clusters resembling pebbles or bobbles across the fabric surface. The stitch is sometimes also called the Bramble Stitch or Blackberry Stitch in other traditions, and it is beloved for the rich three-dimensional texture it produces with minimal complexity.

The two key stitch maneuvers that create the Trinity Stitch texture are:

• (K1, P1, K1) all into the next stitch – working three stitches into a single stitch to create a raised cluster or pebble bump on the fabric surface
• P3tog (Purl 3 stitches together) – reducing three stitches back into one, which draws the cluster together and forms the characteristic rounded pebble shape

These two moves alternate across right-side and wrong-side rows to build up the repeating pebble texture. The remaining stitches in the pattern are standard knit (K) and purl (P) stitches, meaning a knitter only needs to be comfortable with the basic knit and purl actions to complete this project successfully.

The stitch repeat is worked over a cast-on of 82 stitches, and the piece is worked until it measures 40 inches [101.5 cm] in length before being folded in half to create the finished 20-inch square cover.
