Last summer, I found myself completely mesmerized at a butterfly conservatory. A blue morpho landed on my shoulder and stayed there for what felt like forever. My daughter snapped a photo, and I spent the rest of the day thinking about how to capture that iridescent blue in yarn.

That moment became this shawl. I wanted something dramatic enough to turn heads but wearable enough for everyday. Something that would make the person wearing it feel like they had wings of their own.
This Blue Morpho Butterfly Shawl brings together a classic triangular cluster-lace foundation with overlapping shell fans that mimic butterfly scales. The four-piece butterfly appliqué sits on the shoulder like it just landed there. It is an intermediate to advanced project, but I will walk you through every step so you can create something truly spectacular.
What Makes This Shawl Special
This is not your grandmother’s granny triangle. The construction combines several techniques that create visual depth and movement. The base is a traditional cluster-lace triangle worked from the top down. Then you add raised shell fans that overlap like fish scales or butterfly wings. The navy outlines pop against the cobalt blue, and those ivory accents catch the light beautifully.
The star of the show is the detachable butterfly. Made in four pieces with embroidered veins and a tiny tassel body, it transforms a beautiful shawl into wearable art. You can position it wherever you like, or even remove it when you want something simpler.
Important note: This is a reconstructed design. The pattern instructions are complete and detailed, but physical sample testing is still pending. I recommend making a 10-row practice triangle before committing to the full piece. This lets you check your gauge and adjust your hook size if needed.
Materials You Will Need
Yarn:
Hooks:
Notions:
Choose a yarn with good drape. Stiff cotton will not flow the way this design needs to. Look for a soft merino blend, silk blend, or bamboo yarn that feels fluid in your hands.
Finished Size and Gauge
Target dimensions:
Gauge check:
Block a 10-row practice triangle. The long edge should measure about 38 to 40 cm. If your triangle is smaller, go up a hook size. If it is larger, go down. Use the same hook for the entire main shawl once you have confirmed your gauge.
These measurements are targets, not tested sample measurements. Your finished piece may vary slightly depending on your tension and yarn choice.
Abbreviations and Stitch Definitions
Before we dive in, let me define every stitch and abbreviation you will encounter:
Critical note: Turning chains do not count as a stitch unless a step explicitly says they do. Do not mistake the turning chain for a side space when counting.
Triangle Foundation
This section creates the base of your shawl. You will work flat, turning each row. In this section only, chain 3 (ch 3) counts as the first double crochet (dc).
A cluster means 3 dc worked into the same space. Place a removable marker in the center chain-2 space and move it up as you work. The two ends form the straight neck edge, and the marked space forms the lower point.
Row 1 (Color A)
Make an adjustable ring. Ch 3, 2 dc, ch 2, 3 dc into ring. Tighten the ring. Turn.
Count: 2 clusters, 6 dc, 1 center space.
Row 2
Ch 3, 2 dc in first st, ch 1. Work (3 dc, ch 2, 3 dc) in center space. Ch 1, 3 dc in last st (the top of the turning chain). Turn.
Count: 4 clusters, 12 dc, 2 side ch-1 spaces.
Row 3
Ch 3, 2 dc in first st, ch 1. Work 3 dc in the side ch-1 sp, ch 1. Work (3 dc, ch 2, 3 dc) in center. Ch 1, 3 dc in next side ch-1 sp, ch 1. Work 3 dc in last st. Turn.
Count: 6 clusters, 18 dc, 4 side ch-1 spaces.
Rows 4 through 40
Repeat this pattern for each row:
Ch 3, 2 dc in first st, ch 1. Work 3 dc in every side ch-1 space, with ch 1 between clusters and before the center. In center, work (3 dc, ch 2, 3 dc). Ch 1, then 3 dc in each remaining side space, separating clusters with ch 1. Ch 1, 3 dc in last st. Turn.
Keep all rows in Color A.
Count Checks
Use this formula to verify your stitch counts at any row number (n):
Checkpoint counts:
Stop at row 40. Fasten off.
Raised Fans and Edging
This section adds the dimensional shell fans that give the shawl its butterfly-scale texture.
Fan Placement
Lay your triangle right side up with the neck edge horizontal at the top. You will apply fans to rows 12, 14, 16, and every second row through row 38. Use the ch-1 spaces of each selected row.
The fan tops lie over the row above, creating shallow overlapping scales. This adds substantial weight to the shawl, so check the drape after completing two fan rows. If it feels too stiff, loosen your tension slightly.
Working One Fan Row (Color A)
Join Color A with a sl st to the middle dc of the outermost cluster. Work 5 dc into the next ch-1 space, then sl st into the middle dc of the next cluster.
Repeat this pattern toward the center. Fasten off before the center ch-2 space. Do not work fans into the center space.
Repeat separately on the other half of the shawl. Each half has n minus 1 fans on row n.
Fan Outlines (Color B)
For each fan row, join Color B at its first anchor. Sl st loosely through the top of each of the 5 fan dc, then sl st in anchor. Repeat along all the fans on that row.
Keep the strand loose enough that the shawl stays flat. Fasten off at each center and end.
Accent variation: On fan rows 16, 24, and 32, use Color D (ivory) for the middle 3 sl sts of alternate fans. This creates the white accent details visible in the finished piece.
Outer Border Round 1 (Color B)
Join at a neck corner. Along the two sloping edges (the outermost row 40), work sc in each dc and each ch-1 space. Work (sc, ch 2, sc) in the center point.
At the far neck corner, ch 1, then work about 2 sc into each dc row-end along the straight neck edge. Ease the count to avoid rippling. Join to the first sc with a sl st.
Border Round 2
Ch 1, sc in first st. Along each slope, repeat: ch 3, skip 2 sc, sc in next sc.
If 1 or 2 stitches remain at a corner, skip those together. Work (sc, ch 3, sc) into the point.
Work 1 sc per sc along the neck edge. Join and fasten off.
The scallops must lie flat. If they do not, adjust only the final skip at each corner, not the body counts.
Butterfly Pieces
Switch to your 3 mm hook for all butterfly components. The smaller hook creates tighter fabric that holds its shape better.
Upper Wings (Make 2 in Color A)
Ch 3.
Row 1: Sc in second ch and next ch. (2 sts)
Ch 1 and turn each row. The turning ch never counts.
Rows 2 through 10: 2 sc in first st, sc to last st, 2 sc in last st. (Increase 2 each row. Row 10 = 20 sts)
Rows 11 through 14: Sc across. (20 sts)
Rows 15 through 18: Sc2tog, sc to last 2, sc2tog. (18, 16, 14, 12 sts)
Fasten off. The narrow starting end joins the body.
Lower Wings (Make 2 in Color C)
Ch 7.
Round 1: 2 sc in second ch, sc in next 4, 3 sc in last ch. Work down the underside: sc in next 4, sc in last ch beside starting increase. (14 sts)
Mark the first st. Work continuously in rounds.
Round 2: 2 sc in each of first 2 sts, sc 4, 2 sc in each of next 3, sc 4, 2 sc in last st. (20 sts)
Round 3: (sc, inc) twice, sc 4, (sc, inc) three times, sc 4, sc, inc. (26 sts)
Round 4: (2 sc, inc) twice, sc 4, (2 sc, inc) three times, sc 4, 2 sc, inc. (32 sts)
Sl st in next st and fasten off.
Outline and Veins (Colors B and D)
Work sc evenly around each wing in Color B, using 1 sc per stitch and about 1 sc per sc row-end. Add 1 extra sc at any corner that curls.
Embroider 4 radiating lines in Color B from each narrow base toward the outer edge. Use short backstitches without pulling tight.
Add evenly spaced Color D French knots or tiny straight stitches inside the dark outline for the white spots.
Butterfly Body (Color B)
Ch 25. Sc in second ch and each remaining ch. (24 sts)
Work 3 more rows of 24 sc, turning with ch 1.
Fold lengthwise and whipstitch the long edges together, lightly stuffing with yarn ends if desired.
Sew the two upper wings to the upper two-thirds of the body and the lower wings to the lower third. Set wings at slightly upward angles.
Stitch ch-12 antennae to the top and knot the ends. Avoid using wire, as it can poke through the yarn over time.
Assembly and Finishing
Attach the Butterfly
Block wing pieces lightly. Pin the arrangement to your shawl first to find the perfect placement. The pattern suggests the upper right chest area, but position it wherever looks best on you.
Sew the body and wing bases to the shawl. Add small stabilizing tacks halfway along each wing if it flops. Keep all needlework on the fabric surface and do not catch unrelated layers underneath.
A finished wingspan around 25 to 30 cm works well with this shawl size. If yours comes out much larger or smaller, adjust your hook or yarn choice for the next attempt.
Fringe
Cut 32 cm strands in Colors B and D.
Fold 2 strands together. Pull the fold through one border ch-3 loop, then pass tails through the fold and snug the knot.
Repeat in every second border loop along the two slopes, alternating color pairs.
If adding beads: Thread one onto each selected tail and secure with a double knot. Use yarn knots instead if beads are unsuitable for your yarn weight.
Trim to an even 15 cm after blocking.
Butterfly Tassel
Wrap Colors B and D together 20 times around a 16 cm card. Tie the top firmly. Cut the bottom.
Bind 1 cm below the top and sew under the butterfly body. Add an optional bead only if the attachment is secure.
Keep the tassel removable for washing if possible.
Blocking and Care
Soak according to your yarn label instructions. Support all the weight when lifting the wet shawl from the water.
Press between towels and pin the triangle evenly on your blocking mat. Keep the butterfly raised on a folded towel while drying so it does not flatten.
Never hang the wet shawl. Hand wash gently if compatible with your yarn. Dry flat.
Troubleshooting Tips
For a smaller shawl: Stop at an even row number and omit fan rows beyond it. Keep the same count formula.
Cupping (edges curl under): Increase hook size or loosen surface outlines.
Ruffling (edges wave): Remove excess border stitches.
Heavy butterfly: Use lighter yarn or tack wing edges in more places.
Confirm gauge, drape, bead security, and neck comfort on the completed sample before wearing.
Skill Level and Time Estimate
This is an intermediate to advanced project. You should be comfortable with:
The triangle foundation works up relatively quickly once you get into the rhythm. The fans take longer because you are working into the existing fabric. Budget extra time for the butterfly pieces and all the finishing details.
This is not a weekend project, but it is absolutely worth the effort.
