Jace Pillow Cover in Berroco Pima 100 – Knitting Pattern Summary

The Jace Pillow is a thoughtfully designed knitted pillow cover created specifically to fit a Boppy® Original Nursing Support Pillow. Designed by Margaux Hufnagel and published by Berroco, this pattern offers a practical and stylish way to dress up a beloved nursing essential with a handmade, custom-knitted cover. The pattern is available as a downloadable PDF and is rated Intermediate in skill level, making it a satisfying project for knitters who are comfortable with foundational techniques and ready to explore a few more advanced methods.

What Is Being Made

The finished piece is a seamless, stretchy pillow cover designed to slip over a pre-made Boppy® Original Nursing Support Pillow. The cover measures approximately 19 inches / 48.5 cm in circumference when stretched, engineered to hug the curved, crescent-shaped form of the Boppy® pillow snugly. This makes it both a functional and decorative accessory — easy to remove for washing and beautiful enough to display in a nursery or living space.

Techniques Used

• Circular knitting: The cover is worked in the round on a 16-inch / 40 cm circular needle, allowing for a seamless tubular construction that stretches smoothly over the pillow form.
• Provisional cast-on: A provisional cast-on using a crochet hook and waste yarn is required, indicating that the live stitches from the cast-on edge are later rejoined or finished in a specific way — a technique that gives the cover a clean, polished edge and is characteristic of intermediate-level knitting projects.
• Gauge checking and blocking: The pattern emphasizes that gauge should be measured after blocking, making wet or steam blocking an important finishing step to achieve the correct dimensions.

Stitches Used

• Seed Stitch: The primary stitch pattern throughout the cover is Seed Stitch, a classic textured stitch created by alternating knit and purl stitches in a specific sequence so that each stitch sits opposite its neighbor on every row or round. Seed Stitch produces a beautifully bumpy, reversible fabric with excellent elasticity and visual interest. It lies flat without curling, making it ideal for a pillow cover that needs to stretch and maintain its shape. The gauge for this pattern is set at 20 stitches and 32 rounds = 4 inches / 10 cm in Seed Stitch.

Materials – Yarn

The pattern calls for Berroco Pima 100, a 100% Pima cotton yarn sold in 100-gram hanks. This project requires 3 hanks in colorway #8431 Chrysanthemum. Berroco Pima 100 is a worsted-weight yarn known for its smooth, lustrous finish and the exceptional softness that Pima cotton is celebrated for. Pima cotton is a premium long-staple cotton fiber prized for its silky hand feel, durability, and breathability — qualities that make it especially well-suited for a nursing pillow cover that will be handled frequently and laundered regularly. The cotton composition also means the finished cover will be gentle against sensitive skin, an important consideration for a baby-adjacent accessory.

Materials – Needles and Notions

• Needles: A 16-inch / 40 cm circular needle in size US 7 / 4.5 mm is recommended, or the size needed to obtain the correct gauge.
• Notions: A stitch marker to mark the beginning of rounds, a crochet hook and waste yarn for the provisional cast-on, a tapestry needle for finishing, and a pre-made Original Boppy® Nursing Support Pillow (sold separately) to insert into the finished cover.
