One-Piece Sweater Knitting Pattern PDF :Instant Download

A clean, seam-light pullover: knit the body in one piece (front → neckline → shoulders → back), then pick up the sleeves. Only side and underarm seams. Stockinette with rib trims. Measurement-based sizing method included.

Description

Knit a modern, elegant sweater with no shoulder seams and a smooth silhouette. The body is worked in one piece: up the front, shape the neckline, knit short shoulder straps, cast on across the back neck, then work the entire back—so the only sewing is the side seams and sleeve underarms. Sleeves are picked up around the armhole and knit straight, then tapered into ribbed cuffs. The fabric is classic stockinette with 1×1 rib at hem, cuffs, and neck.

This pattern is written in clear steps and includes a swatch-to-size method so you can adapt to any yarn/needle: cast on 10 stitches, measure, then compute the cast-on for your target width. The sample is equivalent to EU 38 with finished measurements below.
