Sewing a Raglan T-Shirt with V-Neck: Complete Step-by-Step Masterclass (Part 2)

Watch Video Lesson

A knit raglan t-shirt featuring a tailored V-neckline is a versatile wardrobe staple that demands precise knitwear construction skills. Unlike a basic round neckband, executing a sharp V-neck collar band requires millimeter accuracy when joining the band miter and clipping the front bodice apex. Any misalignment creates visible wrinkles or bunched fabric across the chest. In Part 2 of this masterclass, we explore the step-by-step assembly of raglan seams, crisp V-neck band shaping, and clean coverstitch hemming.

Required Materials and Machine Setup

• Cotton-elastane jersey knit (95% cotton, 5% spandex, 180 gsm);
• Matching rib knit strip (4.5 cm wide by 45–50 cm);
• Lightweight fusible knit interfacing (2x2 cm square);
• 4-thread differential serger, lockstitch machine with stretch needles (#75);
• Steam iron, tailor's pins, fabric chalk.

Step 1. Attaching Raglan Sleeves to Front and Back

Serge front raglan seams matching alignment notches. Serge one back raglan seam, leaving one back seam open for flat neckband insertion.

Step 2. Measuring and Pre-Pressing the Ribbed V-Neck Band

Cut ribbing strip to 75–80% of total neckline length. Fold in half lengthwise and steam press into a gentle curve.

Step 3. Stitching the Mitered V-Center Apex

Fold band right sides facing at center point. Stitch at a 45-degree angle from folded edge to raw edges. Press seam allowances open to create a crisp mitered point.

Step 4. Clipping Bodice Corner and Serging the Neckband

Reinforce front V apex with fusible interfacing on wrong side. Anchor band apex to front center with a short lockstitch seam. Clip front bodice seam allowance precisely to the stitch line. Serge neckband around entire neckline, stretching ribbing evenly across shoulders and back.

Step 5. Continuous Underarm and Side Seams

Close final back raglan seam. Align underarm intersections and serge side seams continuously from sleeve hem to shirt bottom.

Step 6. Coverstitching Hem and Sleeve Openings

Press 2.5 cm hem allowances and stitch on a coverstitch machine or with a twin needle.
