✂️ Construction Overview

You’ll be making the sweater in pieces or as a top-down raglan (recommended for babies for fewer seams). Below are two style options:


Option 1: Baby Vest (Sleeveless)

Construction: Top-down, seamless, worked in one piece.


Step-by-Step Instructions:

Step 1: Yoke
  1. Foundation Chain: Ch 56

  2. Row 1 (RS): Dc in 4th ch from hook and each across (54 dc)

  3. Row 2 (Yoke Start):

    • Dc in first 8 sts (Left Front)

    • Inc in next st (shoulder marker)

    • Dc in next 10 (Left Sleeve)

    • Inc in next st (shoulder marker)

    • Dc in next 16 (Back)

    • Inc in next st (shoulder marker)

    • Dc in next 10 (Right Sleeve)

    • Inc in next st (shoulder marker)

    • Dc in last 8 (Right Front)

  4. Row 3–8 (or until armhole depth = 4.5″):

    • Dc in each st, inc before and after each raglan stitch (8 increases per row).

    • Use stitch markers to mark raglan points.

Step 2: Separate for Body
  1. When desired yoke depth is reached:

    • Skip sleeve stitches, connect front and back with chain stitches under the arms (usually ch 5).

    • Join with dc to begin working the body in the round or rows.

Step 3: Body
  1. Dc in each st around for 4–5 inches (or desired length).

  2. Finish with 1–2 rows of sc or hdc for a neat edge.

  3. Fasten off and weave in ends.

Step 4: Trim & Finishing
  • Optional edging around armholes and neckline (sc or hdc)

  • Add buttons and button loops if desired


Option 2: Baby Cardigan (with Sleeves)

Construction: Top-down raglan, button-up front


Step-by-Step Instructions:

Step 1: Yoke

Same as vest above, but with 2 extra chains at the start for button band (ch 58 instead of 56).

  • Add 1–2 dc at the start and end of each row to form the front opening and button band.

  • Work yoke rows with raglan increases as before.

Step 2: Separate Sleeves
  • As in vest, when raglan depth is enough (4.5″), separate sleeve stitches.

  • Place sleeve stitches on stitch holders or scrap yarn.

Step 3: Body
  • Continue body in rows (not round) to maintain opening.

  • Add 1–2 edge stitches for button bands on each side.

  • Continue until desired length.

  • Add border in sc, hdc, or fancy stitch (e.g., shell stitch).

  • Sew on buttons on one side, add loops or buttonholes on the other.

Step 4: Sleeves
  • Join yarn at armhole.

  • Work dc or hdc rounds for 6–7 inches.

  • Optional: taper sleeves by decreasing 2 sts every 3–4 rounds.

  • End with 1–2 rounds of sc.


Tips:

  • Customize with stripes, colorwork, or bobble stitches.

  • Add cute appliqués (e.g., hearts, stars, animals) for decoration.

  • For warmer garments, use wool-blend yarns.

  • For summer versions, use cotton yarn and a lacier stitch (e.g., V-stitch).
