Yarn: Medium-weight (worsted) merino wool or acrylic yarns are ideal for beginners—they’re forgiving and easy to handle. Choose a rich color or neutral tone to suit your skill level.
Needles: Size 8–10 (5–6 mm) straight or circular needles match most medium-weight yarns.

Final Thoughts

1. Cast On
Start by casting on 20–25 stitches (adjust based on desired width). The long-tail cast-on is highly recommended for its stretch and neatness.

2. Knit the Main Body
Work alternating rows of stockinette stitch (knit every row) for the front and back. Keep tension even to avoid ladders or gaps.

3. Shape for Fit
Create gentle shaping at the shoulders and sleeves:

Shoulders: Either knit the body straight (instrumental for a boxy shape) or reach a few rows earlier to knit in the round or increase sparingly.
Sleeves: Knit sleeves to length, then shape—ease the yoke inward gently for comfort.

4. Bind Off
Securely finish with a stretchy bind-off to prevent the jumper from curling or snagging.

Tips for Success

Practice tension evenly—practice swatches first.
Use stitch markers to track stockinette rows.
Block gently after knitting to even out seams and enhance flow.
Add personal details: color blocking, ribbing edges, or simple lace inserts.
