Celestial Sun and Moon Crochet Cardigan Outfit – Free Pattern

This celestial sun and moon crochet cardigan outfit is an original Witchy Crochet design built from measured half-double-crochet panels. The relaxed M/L fit has a 42-inch finished chest, a clean open front, practical sleeves, and carefully placed decorative crochet details.

The back and two fronts are worked from the lower edge upward, while each sleeve is worked flat from wrist to upper arm. Straight seams make the garment approachable, and the decorative pieces are blocked separately before being sewn to the completed cardigan.

Why You’ll Love This Project

The dense body fabric is warm enough for autumn layering, yet the straightforward panel plan makes every measurement easy to verify. The decoration can be positioned after assembly, so the balance is visible before a single motif is attached.

Materials

• Approximately 1,650 yards worsted-weight yarn in matte black for the body
• 280 yards worsted-weight yarn divided among antique gold, cream, rust, and dusk blue
• 5 mm crochet hook, or size needed to obtain gauge
• 4.5 mm crochet hook for cuffs and edging
• Twelve locking stitch markers
• Tape measure
• Yarn needle
• Scissors
• Washable blocking mat and rustproof pins

Gauge, Measurements, and Planning

At the stated gauge, 72 back stitches measure about 20.5 inches and each 36-stitch front measures about 10.25 inches. Together they create a 41–42 inch circumference after relaxed blocking. Fifty-two rows measure about 21 inches. Correct stitch gauge before changing the written counts.

Make and wash a gauge swatch before beginning. Measure only after the swatch is completely dry. If the stitch width differs, change hook size rather than pulling the working yarn tighter. Keep a written count at the end of every section so the finished edges remain balanced and the assembly points line up.

Abbreviations and Special Stitches

• ch: chain
• hdc: half double crochet
• sc: single crochet
• dc: double crochet
• sl st: slip stitch
• st(s): stitch(es)
• rnd: round

Special stitch guidance: Work half double crochet through both loops. Complete every color change on the final yarn-over of the previous stitch. Beginning chains do not count as stitches.

Important Notes

• The pattern is written for a relaxed adult M/L with approximately 4 inches of positive ease.
• To add roughly 2.25 inches to the chest, add 4 stitches to the back and 2 stitches to each front; keep all three panel counts even.
• Chain 2 at the start of a body row, turn, and place the first hdc in the first stitch.
• Block all five garment panels to measurement before seaming and block every applique before placement.

Complete Instructions for Celestial Sun and Moon Crochet Cardigan Outfit

Crochet the Back Panel

Use matte black and keep the lower edge relaxed.

1. Foundation Row: Chain 74. Hdc in the third chain from the hook and in each remaining chain. Mark the first and last stitch, chain 2, and turn. (72 sts)
2. Back Rows 2–52: Hdc in every stitch, chain 2, and turn after every row except the last. Count at Rows 10, 20, 30, 40, and 52. (72 sts)
3. Fasten off after Row 52. The panel should measure approximately 20.5 inches wide and 21 inches long after blocking.

Crochet Two Front Panels

Make two identical rectangles; mark the inner opening edge of each.

1. Chain 38. Hdc in the third chain from the hook and across, chain 2, and turn. (36 sts)
2. Work even in hdc through Row 52, turning after every row except the last. (36 sts)
3. Fasten off and block each front to approximately 10.25 inches wide and 21 inches long. Place the marked opening edges toward the center.

Crochet Two Sleeves and Cuffs

The long direction of each row runs from cuff to upper arm.

1. Chain 69. Hdc in the third chain from the hook and across, chain 2, and turn. (67 sts)
2. Work even through Row 36. Fasten off, block to 19 inches long and approximately 14.5 inches around before seaming. (67 sts)
3. With the 4.5 mm hook, join black yarn at the cuff edge and work 8 rows of 8 back-loop sc perpendicular to the sleeve edge, slip-stitch joining each short row to the cuff. Fasten off.

Join the Cardigan

Use mattress stitch with right sides facing outward.

1. Align one front with each side of the back. Sew 30 stitches of each shoulder from the outer edge inward, leaving 12 back stitches and 6 stitches on each front unseamed for the neck opening.
2. Measure 8 inches down from every shoulder and place an armhole marker. Sew each side seam from the lower edge to its marker.
3. Fold each sleeve lengthwise and sew its long seam. Match the sleeve seam to the body side seam, pin the sleeve cap evenly around the armhole, and sew without stretching either edge.

Crochet the Sun, Moon, and Starburst Motifs

Use midnight navy, antique gold, warm cream, rust, and dusk blue and keep all decorative tails on the wrong side.

1. Make one sun medallion. With antique gold, work 12 dc in a magic ring; in the next round alternate [dc, ch 2] around, then add eight chain rays to the outer edge.
2. Make one crescent moon by crocheting a cream circle of 36 dc and overlaying one side with dusk blue, sewing only the curved edge to leave a clean crescent.
3. Make 8 starbursts in cream or rust: repeat [sc, ch 3, slip stitch in the second and third chains] five times from a magic ring.
4. Place the sun high on the back, the moon on the left front, and four starbursts on each sleeve; sew through every ray and point.
5. Add a narrow rust edging around the sun and moon, then block all motifs flat without flattening their raised centers.

Add the Front and Neck Edging

Keep the right side facing and use the 4.5 mm hook.

1. Join charcoal or black at the lower right front. Work sc evenly up the right front, around the back neck, and down the left front, placing approximately 3 sc for every 4 row ends. Do not pull the edge tight.
2. Chain 1, turn, and work one more sc row across the full opening. Fasten off and block the edging flat.
3. Optional tie: Chain 181, slip stitch in the second chain and every remaining chain, then fasten off. Thread the tie through the side seams at natural waist level.

Assembly and Shaping

After blocking, match the garment centers first: mark the back neck midpoint, both shoulder endpoints, both armhole depths, and each sleeve midpoint. Pin between markers at equal intervals before seaming. This prevents one panel from feeding faster than another and keeps the themed decorations level when the cardigan is worn.

Lay every component on a flat surface before joining. Match the marked centers first, then divide each remaining edge into equal sections. Work through both layers with consistent tension and pause after each section to check that the fabric lies flat. This measured approach prevents twisting and keeps decorative details facing the intended direction.

Finishing

1. Weave every body tail through at least four same-color stitches, reverse direction once, and trim.
2. Secure each decorative motif at its outer edge and at several inner points so it cannot fold or snag.
3. Wet-block the cardigan to the listed chest, length, and sleeve measurements without flattening raised details.
4. Let the garment dry completely, try it on over a light layer, and inspect every shoulder, sleeve, pocket, applique, and edging join.

For a polished result, weave each tail through several same-color stitches, reverse direction once, and trim only after the fabric has been gently stretched. Block to the listed dimensions without flattening textured stitches. Inspect joins, borders, straps, and decorative pieces before the project is used or gifted.

Helpful Tips

• Make and wash a 6-inch gauge swatch before beginning the back panel.
• Count every tenth body row and place a removable marker so both fronts finish at the same length.
• Use black sewing thread only for temporary placement; complete all permanent joins with matching yarn.
• Photograph the pinned decoration layout before sewing so spacing remains balanced while individual pieces are lifted.

Good lighting and a contrasting stitch marker make counting much easier. If a section looks uneven, compare the current count with the previous checkpoint before continuing. Fixing one missed stitch early is faster than compensating later, and it preserves the measurements used by the assembly instructions.

Frequently Asked Questions

How do I adjust the cardigan width?

Add or remove stitches in sets of 4 on the back and matching sets of 2 on each front. Make a new gauge calculation and preserve even stitch counts.

Can I make the cardigan longer?

Yes. Add the same number of rows to the back and both fronts before shoulder assembly; five rows add about 2 inches at the stated gauge.

How should I wash the finished cardigan?

Hand-wash in cool water, support the wet garment fully, press moisture into towels, reshape to measurement, and dry flat away from direct heat.

Conclusion

The finished celestial sun and moon crochet cardigan outfit combines dependable panel construction with a radiant sun medallion, one crescent moon, and eight tiny starbursts. Careful counting, measured seams, and separately blocked decorations give this original Halloween-ready layer a polished handmade finish.
