Sirdar Raglan Fair Isle Sweater Jumper Knitting Pattern

Sirdar Raglan Fair Isle Sweater for Babies

What is Being Made

This is an advanced-level knitted raglan sweater designed for babies aged 0-24 months. The garment features a classic Fair Isle patterned yoke with a charming Nordic-inspired design, creating a decorative colorwork element across the chest and shoulders. The sweater is sized to grow with your baby, with six size options ranging from newborn (0-3 months) through 18-24 months, with chest measurements from 42 cm to 56 cm. The full length varies from 25 cm for the smallest size to 36 cm for the largest, ensuring proper proportions for each age group.

Techniques Used

This pattern employs Fair Isle knitting, a traditional colorwork technique that involves carrying multiple yarn colors across the row to create intricate patterned designs. The Fair Isle yoke is the focal point of this sweater, adding visual interest and a folksy, fairy-tale aesthetic. The raglan construction is used for the sleeve shaping, where the sleeve cap decreases are worked diagonally from the underarm to the neckline, creating a seamless transition from body to sleeve. This construction method is particularly popular for baby garments as it provides excellent fit and comfort. The pattern requires careful tension management when working with multiple colors to ensure even, professional-looking colorwork.

Stitches Used

The primary stitch used in this sweater is Stocking Stitch (also called stockinette stitch), which creates a smooth, classic fabric ideal for baby garments. Stocking Stitch is worked by alternating knit rows on the right side with purl rows on the wrong side, producing the characteristic V-pattern texture. For the Fair Isle colorwork sections, the same Stocking Stitch base is maintained while introducing the secondary colors to create the patterned design. The gauge for Stocking Stitch is 22 stitches over 10 cm (4 inches) when measured over 28 rows, while the Fair Isle sections work to a slightly different gauge of 24 stitches over 10 cm measured over 26 rows, reflecting the subtle density changes that occur when working with multiple colors.

Materials and Yarn

This pattern is designed to be worked with Sirdar Snuggly Cashmere Merino Silk in Double Knitting weight, a luxurious blend specifically formulated for baby garments. The yarn combines cashmere, merino wool, and silk fibers to create an exceptionally soft, gentle fabric that is kind to delicate baby skin. The yarn is machine washable, making it practical for frequent laundering while maintaining its softness through repeated washing.

The pattern requires three coordinating yarn colors (designated as Yarn A, Yarn B, and Yarn C), with yardage varying by size. For the smallest size (0-3 months), you will need 2 balls of Yarn A, plus 1 ball each of Yarn B and Yarn C. Larger sizes require 3-4 balls of Yarn A depending on the age group, while Yarn B and Yarn C remain constant at 1 ball each across all sizes. The pattern recommends choosing from the available Sirdar Snuggly Cashmere Merino Silk colorway options, which include shades such as Pied Piper, Red Riding Hood, Enchanted Castle, and Midnight, each evoking a fairy-tale aesthetic.

Standard knitting needles appropriate for Double Knitting weight yarn are required to achieve the specified gauge of 22 stitches per 10 cm. Maintaining consistent tension is particularly important when transitioning between single-color and Fair Isle sections to ensure the finished garment has even appearance throughout.
