Step-by-Step Instructions: The Sweater

Back Panel

Cast On and Ribbing: Cast on 48 (52, 56) stitches. Work in k2, p2 ribbing for 1 inch. Row 1 (RS): k2, p2, repeat to end. Row 2 (WS): p2, k2, repeat to end. Repeat these 2 rows until ribbing measures 1 inch.

Stockinette Section: Switch to stockinette stitch (knit on RS, purl on WS) and work for 2 inches, ending with a WS row.

Begin Honeycomb Cable Pattern: Now comes the beautiful part! Work these 4 rows:

• Row 1 (RS): k4 (5, 6), *C4F, C4B, k4; repeat from * to last 4 (5, 6) stitches, k4 (5, 6).
• Row 2 (WS): Purl all stitches.
• Row 3 (RS): Knit all stitches.
• Row 4 (WS): Purl all stitches.

Repeat these 4 rows until the piece measures 6 (7, 8) inches from the cast-on edge, ending with a WS row.

Shape Armholes: Bind off 3 (3, 4) stitches at the beginning of the next 2 rows. Continue in pattern until the armhole measures 3 (3.5, 4) inches, ending with a WS row.

Shape Shoulders: Bind off 6 (7, 7) stitches at the beginning of the next 2 rows, then 6 (6, 7) stitches at the beginning of the next 2 rows. Bind off the remaining 18 (20, 20) stitches for the back neck.

Front Panel

Work the front panel exactly as you did the back, until the armhole shaping is complete. Continue in pattern until the armhole measures 2 (2.5, 3) inches, ending with a WS row.

Shape Neck: Next row (RS): Work in pattern across 14 (15, 16) stitches, join a second ball of yarn, bind off the center 10 (12, 12) stitches, work to end. Now you'll work both sides at once, decreasing 1 stitch at each neck edge every other row 3 times. Continue in pattern until the armhole measures the same as the back. Bind off the remaining 6 (7, 7) and 6 (6, 7) stitches for each shoulder.

Sleeves (Make 2)

Cast on 24 (26, 28) stitches. Work k2, p2 ribbing for 1 inch. Switch to stockinette stitch. Increase 1 stitch at each end of every 4th row until you have 36 (40, 44) stitches. Work even until the sleeve measures 5 (6, 7) inches from the cast-on edge, ending with a WS row. Bind off all stitches loosely.

Sweater Finishing

Sew the shoulder seams. Set in the sleeves, sewing the sleeve caps to the armholes. Sew the side and sleeve seams.

Neckband: With the right side facing, pick up and knit 44 (48, 52) stitches around the neck edge. Work k2, p2 ribbing for 1 inch. Bind off in pattern. Weave in all ends and block gently.

Step-by-Step Instructions: The Pants

Left Leg

Cast on 36 (40, 44) stitches. Work k2, p2 ribbing for 1 inch. Switch to stockinette stitch. Increase 1 stitch at each end of every 4th row until you have 48 (54, 60) stitches. Work even until the leg measures 5 (6, 7) inches from the cast-on edge, ending with a WS row. Place the stitches on a holder.

Right Leg

Make the right leg identically to the left leg.

Pants Body

With the right side facing, knit across the left leg stitches, then the right leg stitches onto one needle—you'll now have 96 (108, 120) stitches. Place a marker at the center front and center back.

Work even in stockinette stitch for 3 (3.5, 4) inches.

Decrease Round: k2tog, knit to 2 stitches before the center back marker, ssk, sm, k2tog, knit to 2 stitches before the center front marker, ssk. Repeat this decrease round every 4th row 3 times total. You'll now have 84 (96, 108) stitches.

Work even until the body measures 6 (7, 8) inches from the crotch, ending with a WS row. Work k2, p2 ribbing for 1 inch. Bind off in pattern.

Pants Finishing

Tips for Perfect Results

Take your time with the honeycomb cable pattern—it's easier than it looks! The key is keeping your tension consistent. Use stitch markers to help you keep track of your pattern repeats, and don't be afraid to use a lifeline if you're worried about making mistakes.

When blocking your finished set, use a gentle wool wash and lay flat to dry. This will help the cables relax and show their beautiful texture. The honeycomb pattern will bloom beautifully after blocking, revealing its full dimensional charm.

This heirloom-quality set makes a wonderful gift for baby showers, christenings, or any special occasion. The timeless design and soft yellow color will be treasured for years to come—and perhaps even passed down to the next generation. Happy knitting!
