900 Obsidian - Jumper Knitting Pattern for Women in Valley Yarns Granville

900 Obsidian – Women's Lace Jumper Knitting Pattern by Julie Turjoman in Valley Yarns Granville

The 900 Obsidian is a beautifully versatile women's pullover jumper designed by Julie Turjoman and knitted in Valley Yarns Granville, a refined sport-weight yarn. Styled with elegant simplicity, this top is equally at home under a blazer at the office, dressed up for an evening out, or paired with jeans for a relaxed weekend look. The defining feature of the design is its striking arrow lace panels, which run vertically through the fabric and are given exceptional clarity and crispness by Granville's cotton-dominant blend.

Techniques Used

This pattern is classified as intermediate difficulty, making it an excellent project for knitters who are comfortable with the basics and ready to develop their lace and seamless construction skills. The following techniques are employed throughout:

• Bottom-up construction: The jumper is built from the cast-on edge upward, a traditional and intuitive approach that allows for easy length adjustments as you go.
• Worked in the round: Circular knitting is used for the body of the jumper, eliminating side seams and producing a smooth, continuous fabric.
• Worked flat: Certain sections of the garment are worked back and forth in rows, adding structural shaping where needed.
• Seamless construction: The overall design minimises or eliminates seaming, resulting in a polished, professional finish with less finishing work required.
• Lace knitting: The signature arrow lace panels are created using an 8-row repeating lace pattern. Lace knitting typically involves yarn-overs paired with decreases to form decorative openwork motifs. Here, the arrow motif gives the fabric a geometric, directional quality that adds sophistication without overwhelming the design.

Stitches Used

• Lace stitch pattern (8-row repeat forming the arrow lace panels) – the primary stitch pattern of the garment
• Yarn-overs and decreases – the building blocks of the lace motifs
• Cast on (CO) and bind off (BO) – standard construction stitches
• General knit and purl stitches as part of the overall fabric and any ribbing or edging sections

Gauge: 22 stitches and 28 rounds = 4 inches in Lace stitch, blocked. Blocking is an important finishing step for lace knitting, as it opens up the lace motifs and evens out the fabric for the best stitch definition and accurate sizing.

Yarn and Materials

The pattern calls for Valley Yarns Granville, a sport-weight yarn composed of 90% Pima Cotton and 10% Merino Wool, sold in 50g/167-yard skeins. The cotton content gives the yarn excellent stitch definition and a cool, breathable hand, while the merino wool adds a subtle softness and elasticity that makes it a pleasure to knit with.
