Plymouth Yarn F153 – OH MY! Baby Blankie with Heaven Trim: Free Knitting Pattern Summary

This free downloadable knitting pattern from Plymouth Yarn Design Studio (pattern number F153) produces a soft, cozy baby blanket perfectly sized for everyday use, including the car seat. The finished blanket measures approximately 18 x 21 inches, making it a compact yet practical project for new parents, gift-givers, and knitters looking for a quick and satisfying make. The pattern is available free with yarn purchase and is suitable for knitters who are comfortable with basic techniques.

What Is Being Made

The project is a small baby blanket — referred to as the Baby Blankie — constructed in two distinct sections: a central stockinette panel and a surrounding garter stitch border. The center panel measures approximately 13.5 x 16 inches before the border is added, and the completed border brings the total dimensions to roughly 18 x 21 inches. The two-yarn, two-texture design gives the blanket a polished, boutique appearance while remaining straightforward to knit.

Materials Required

• Plymouth Yarn Oh My! – 2 balls, used for the central stockinette panel
• Plymouth Yarn Heaven – 2 balls, used for the garter stitch border trim
• Knitting needles: US Size 10.5 (for the Oh My! center) and US Size 13 (for the Heaven border), or the size needed to achieve gauge

Gauge

• 3.5 stitches = 1 inch over stockinette stitch on US Size 10.5 needles with Plymouth Yarn Oh My!
• 2.5 stitches = 1 inch over garter stitch on US Size 13 needles with Plymouth Yarn Heaven

Techniques Used

• Casting on loosely – The pattern specifies a loose cast-on for the center panel, which helps maintain the drape and stretch appropriate for a baby blanket.
• Stockinette stitch (St st) – The main body of the blanket is worked entirely in stockinette stitch, alternating knit rows on the right side and purl rows on the wrong side to create a smooth, classic fabric.
• Binding off – Standard bind-off is used to finish the center panel before the border is applied.
• Picking up and knitting stitches – The Heaven border is worked by picking up stitches along each edge of the finished center panel, a technique that creates a seamless, integrated look between the body and the trim.
• Garter stitch – The border is worked in garter stitch (knitting every row), which creates a ridged, reversible fabric with natural edge stability — ideal for a border treatment.
• Increasing – To shape the border and create mitered or flared corners, the pattern instructs the knitter to increase one stitch at each end of every other row throughout the border section.

Stitches Used

• Stockinette stitch – Used for the Oh My! center panel; produces a smooth knit face and a textured purl reverse.
• Garter stitch – Used for the Heaven border; produced by knitting every row, resulting in a dense, stretchy, and decorative trim.

Construction Notes

The blanket is constructed in a logical sequence. The Oh My! center panel is knitted first: 47 stitches are cast on loosely with US Size 10.5 needles and worked in stockinette stitch until the piece reaches 16 inches in length, ending on a wrong-side row before binding off. The border is then added in two stages using Plymouth Yarn Heaven and the larger US Size 13 needles. First, 36 stitches are picked up along each short end; after an initial knit row, garter stitch is worked with increases at each end every other row until the border reaches 2.5 inches. The long sides are then treated similarly, with 41 stitches picked up along each long
