Materials Required

  • Crochet Hook: Suitable for yarn size (5.5 mm)
  • Tapestry Needle: For weaving ends and sewing portions
  • Scissors

Special Features

  • Construction: Includes body, sleeves, and edging sections worked seamlessly for a polished result.
  • Customization: Easy to adjust sizing and color schemes to suit personal preferences.
  • Styling: Perfect as a gift for babies, offering comfort and playful patterns.

Level of Difficulty

Intermediate. While straightforward stitches like single and double crochet are used, techniques such as alternative double crochet and popcorn stitch require slight precision and practice.


Tutor's Suggestions

  • Alternative Double Crochet: Use this method instead of chain-3 for a cleaner and sturdier start to rows.
  • Popcorn Stitch: Ensure consistent tension when pulling through all loops for uniform texture.
  • Color Changes: Always join the next color in the last stitch of each row to maintain neat transitions.

Step-by-Step Instructions

Body Section

  1. Row 1: Begin by making a slip knot and chaining 66. Double crochet in the fourth chain from the hook and continue double crochet for the next 10 chains.
    • Perform a double increase in the next chain — 2 double crochets, 1 chain, and 2 double crochets.
    • Follow the sequence: 8 double crochet stitches, perform double increase. Continue with 20 double crochets, another double increase. End with 12 double crochet stitches.
  2. Row 2: Turn your work. Start with alternative double crochet (replace chain-3). Double crochet in each stitch across. When you encounter chain-1 spaces from Row 1, do a single increase (1 double crochet, chain 1, and 1 double crochet).

  3. Row 3 to Row 12: Repeat rows 2 and 3 alternately. At the end of each row, change colors to transition through the rainbow palette.

Separating Body and Sleeves (Row 13):

  1. Crochet across front, marking sleeves by skipping stitches (skip 44 stitches for each sleeve opening). Continue crocheting for the body sections.
  2. For Row 14, increase stitches evenly across this row (21 stitches added).

  3. Work rows of double crochet in rainbow color sequence for Row 15 through Row 19, transitioning colors every two rows.

Popcorn Method (Row 20):

  1. Begin single crochet in the first two stitches.
  2. Make a popcorn stitch in the next stitch (complete 5 unfinished double crochets, then pull through all loops).
  3. Add chain-1, single crochet in the next two stitches. Repeat popcorn stitch across the row.
  4. Continue alternating rows of popcorn stitch with rows of double crochet.

Sleeves Pattern:

  1. With the back side facing, join yarn at the underarm area. Work single crochet, popcorn stitches, and chain-1 spaces back and forth (repeat rows 2 and 3 as done for the body).
  2. When the sleeve is complete, sew the underarm together using the whip stitch method. Repeat for the second sleeve.

Edging and Finishing:

  1. Flip the cardigan upside down. Join the yarn to one corner and single crochet across each stitch, adding extra crochet stitches at corners for shape.
  2. Continue working clean edging and fasten off your yarn. Weave in all loose ends for a neat finish.
