Materials Needed

Before you begin, gather the following materials to ensure a smooth knitting experience:

• Yarn: Worsted weight yarn in heathered sage green (approximately 1200-1400 yards for sizes S-M). Choose a soft, breathable fiber like merino or a merino blend for the best drape and comfort.
• Needles: US 7 (4.5 mm) circular needles (32-inch or longer) for the main body, and US 5 (3.75 mm) needles for ribbing. The circular needle allows you to accommodate the large number of stitches comfortably.
• Gauge: 20 stitches and 28 rows = 4 inches in stockinette stitch on larger needles, after blocking. Always knit a gauge swatch and block it before starting to ensure your finished garment matches the intended measurements.
• Notions: Stitch markers (at least 8), tapestry needle for weaving in ends, sewing needle and thread for buttons, and 7 buttons (approximately 1/2 inch in diameter).

Special Stitch – Leaf Lace Panel (worked over 12 stitches)

This is the signature motif of the cardigan, resembling fern fronds or pine needles. Work this panel between markers as directed in the pattern.

• Row 1 (RS): k2, yo, ssk, k6, k2tog, yo, k2
• Row 2 and all WS rows: purl all stitches
• Row 3: k3, yo, ssk, k4, k2tog, yo, k3
• Row 5: k4, yo, ssk, k2, k2tog, yo, k4
• Row 7: k5, yo, ssk, k2tog, yo, k5
• Row 9: k4, k2tog, yo, k2, yo, ssk, k4
• Row 11: k3, k2tog, yo, k4, yo, ssk, k3
• Row 13: k2, k2tog, yo, k6, yo, ssk, k2
• Row 15: k1, k2tog, yo, k8, yo, ssk, k1
• Row 16: purl

Repeat rows 1-16 for the pattern. The yarn overs create the openwork, while the decreases keep the stitch count consistent at 12 stitches per panel.

Back Panel

With smaller needles (US 5), cast on 90 (100, 110) stitches. Work in k1, p1 ribbing for 2 inches. This creates a neat, stretchy hem that will hold its shape.

Switch to larger needles (US 7). Work in stockinette stitch (knit on RS, purl on WS) until the piece measures 12 inches from the cast-on edge, ending with a WS row. This smooth stockinette provides a calm backdrop for the lace panels.

Begin Lace Pattern

Row 1 (RS): k3 (5, 7), pm, work Leaf Lace Panel over next 12 stitches, pm, k60 (66, 72), pm, work Leaf Lace Panel over next 12 stitches, pm, k3 (5, 7).

Continue in this manner, working stockinette between markers and lace panels, until the piece measures 20 inches from the cast-on edge, ending with a WS row. The lace panels will be positioned symmetrically on either side of the center, creating a beautiful botanical frame.

Armhole Shaping

Bind off 4 (5, 6) stitches at the beginning of the next 2 rows. This creates the armhole opening. Then, decrease 1 stitch at each edge every RS row 4 (5, 6) times – 74 (80, 86) stitches remain. To decrease at the beginning of a row, ssk; at the end of a row, k2tog.

Continue straight (without further decreases) until the armhole measures 8 (9, 10) inches from the bind-off edge. End with a WS row.

Shoulder Shaping

Bind off 8 (9, 10) stitches at the beginning of the next 4 rows, then 7 (8, 9) stitches at the beginning of the next 2 rows. This creates a sloped shoulder. Bind off the remaining 28 (30, 32) stitches for the back neck. These stitches will be picked up later for the neckband.

Left Front Panel

With smaller needles, cast on 45 (50, 55) stitches. Work in k1, p1 ribbing for 2 inches. Switch to larger needles and work in stockinette until the piece measures 12 inches from the cast-on edge, ending with a WS row.

Begin Lace Pattern

Row 1 (RS): k3 (5, 7), pm, work Leaf Lace Panel over next 12 stitches, pm, knit to end. The lace panel will be positioned at the center front edge, creating a beautiful cascading effect.

Continue as established until the piece measures 18 inches from the cast-on edge, ending with a RS row. This is slightly shorter than the back to allow for the neck shaping.

Neck Shaping

At the neck edge (beginning of RS rows), bind off 6 stitches once. Then, decrease 1 stitch every RS row 10 times – 29 (34, 39) stitches remain. To decrease at the neck edge, work to the last 2 stitches, then k2tog. Continue straight until the armhole measures the same as the back (8 (9, 10) inches from the bind-off edge).

Shoulder Shaping

Bind off 8 (9, 10) stitches at the armhole edge every RS row 3 times, then 7 (8, 9) stitches once. The armhole edge is the opposite side from the neck edge. Bind off all remaining stitches.

Right Front Panel

Work as for the left front, but mirror the lace placement (lace panel at the end of RS rows) and neck shaping at the end of RS rows. To mirror the lace panel, work: knit to last 15 (17, 19) stitches, pm, work Leaf Lace Panel over next 12 stitches, pm, k3 (5, 7). For neck shaping, work to the last 2 stitches, then ssk.

Sleeves (make 2)

With smaller needles, cast on 50 (55, 60) stitches. Work in k1, p1 ribbing for 2 inches. Switch to larger needles and work in stockinette, increasing 1 stitch at each edge every 6th row 12 (14, 16) times – 74 (83, 92) stitches. To increase, pick up the bar between stitches and knit it through the back loop (M1L on the right side, M1R on the left side).

When the sleeve measures 16 inches from the cast-on edge, begin the lace panel in the center: k31 (36, 41), pm, work Leaf Lace Panel over 12 stitches, pm, knit to end. Continue until the sleeve measures 18 inches from the cast-on edge, ending with a WS row.

Cap Shaping

Bind off 4 (5, 6) stitches at the beginning of the next 2 rows. Decrease 1 stitch at each edge every RS row 12 (14, 16) times, then every row 6 (7, 8) times. Bind off the remaining stitches. The cap shaping creates a smooth, rounded sleeve head that fits neatly into the armhole.

Finishing

Block all pieces to the measurements specified in the pattern. This is crucial for lace work – it opens up the stitches and gives the cardigan its beautiful drape. Pin each piece to a blocking mat, spray with water, and allow to dry completely.

Sew the shoulder seams using a mattress stitch for a seamless finish. Set in the sleeves, matching the center of the sleeve cap to the shoulder seam. Sew the side and sleeve seams.

Neckband

With smaller needles, pick up and knit 90 (100, 110) stitches around the neckline. Work in k1, p1 ribbing for 1 inch. Bind off loosely in pattern. To bind off loosely, use a larger needle or work the bind-off in pattern (knit the knits and purl the purls).

Button Band (left front for women)

With smaller needles, pick up and knit 1 stitch for every row along the left front edge. Work in k1, p1 ribbing for 1 inch. Bind off. The button band is worked on the left front for women's garments (right front for men's).

Buttonhole Band (right front)

Work as for the button band, but on the 4th row, create 7 buttonholes evenly spaced (k2tog, yo). To space them evenly, divide the total number of stitches by 7 to determine the spacing. Continue ribbing for 1 inch total. Bind off. Sew buttons opposite the buttonholes. Weave in all ends with a tapestry needle.
