Bordered Triangles Baby Blanket – Knitting Pattern by Jill Ramos in Cascade Yarns

The Bordered Triangles Baby Blanket is a charming, intermediate-level knitting pattern designed by Jill Ramos and published by Cascade Yarns as a free downloadable PDF. This cozy knitted baby blanket is built from modular triangles that radiate in all directions, creating a dynamic, eye-catching geometric design that is as enjoyable to knit as it is to gift. The finished blanket comes in two sizes: 27 inches square or 33 inches square, making it a versatile project for newborns and growing babies alike.

What Is Being Made

This pattern produces a square baby blanket constructed using a modular, geometric approach. Rather than knitting the blanket in a single flat piece from cast-on to bind-off, the design is assembled from individual triangular sections that work outward in multiple directions. The result is a visually striking blanket with a strong sense of movement and dimension, finished with a coordinating border that frames the triangular interior neatly.

Yarn and Materials

The pattern calls for Cascade 128 Superwash yarn in two distinct versions, used across three color roles:

• Color A: Cascade 128 Superwash Multis in color 106 — 2 skeins for the smaller size, 3 skeins for the larger size
• Color B: Cascade 128 Superwash in color 826 — 2 skeins for the smaller size, 3 skeins for the larger size
• Color C: Cascade 128 Superwash in color 820 — 1 skein for the smaller size, 2 skeins for the larger size

Cascade 128 Superwash is a chunky weight yarn sold in 100-gram skeins. Its superwash treatment makes it machine washable — a highly practical quality for baby items that will need frequent laundering. The multicolored version used for Color A adds natural color variation and visual interest without requiring complex colorwork techniques.

Needles and Other Supplies

The pattern requires size 10 circular needles in two cord lengths: a 24-inch circular needle and a 36-inch circular needle, or the size needed to achieve the correct gauge. Circular needles are used here both for flat knitting and for working in the round during the border section, accommodating the large stitch count comfortably. Additional supplies include stitch markers and a tapestry needle for finishing and weaving in ends.

Gauge

The gauge for this pattern is 14 stitches and 30 rows over 4 inches in Garter Stitch. Achieving the correct gauge is important to ensure the blanket reaches its intended finished dimensions, so knitters are encouraged to swatch before beginning.

Techniques and Construction

This blanket is a modular knitting project, a technique in which individual geometric units are knitted separately or sequentially and joined as the work progresses, rather than shaping the entire piece at once. Modular knitting is a wonderful way to maintain interest throughout a larger project, as each triangle feels like a small, satisfying accomplishment. The triangles in this design play out in multiple directions, giving the blanket its signature radial, dynamic appearance.

The construction combines both flat knitting and knitting in the round, which is why two different circular needle lengths are specified. The border is worked in the round, encasing the modular interior in a clean, unified frame.

Stitches Used

The primary stitch throughout this pattern is Garter Stitch, which is achieved by knitting every row when working flat, or by alternating one knit round and one purl round when working in the round. Garter Stitch produces a squishy, reversible fabric with horizontal ridges — ideal for a baby blanket that needs to be soft, stretchy, and cozy on both sides.
