Pattern highlights
- Start at the neck with a small foundation chain and build outward in rings of chain and double crochet.
- Grow the yoke evenly across left sleeve, back, and right sleeve until it reaches the underarm depth you want.
- Separate the piece by counting shells from center, then bridge each underarm with a short chain of its own.
- Continue the body in the established shell pattern, working straight down until it reaches your desired length.
- Come back to the sleeves and work them separately to whatever length suits you.
- Finish the neckline with the smaller hook, then weave in ends and block the whole jacket.
About This Pattern
This one goes in the garment shelf of my notebook, next to the pieces I pull out once summer cotton season starts. A top-down sleeved jacket isn't rare, but this one begins at the neck with a ring of chains and grows outward in every direction at once. I like logging pieces where the shaping happens invisibly, in the count of shells rather than in short rows. It's a jacket that starts as a small ring and ends as a whole garment.
What comes off the hook is light enough to wear indoors on a cool evening, dense enough to layer over a sleeveless top. The shell pattern reads as lace without being fussy about tension. Sleeves and hem length are both yours to decide, so the same set of instructions can turn into a cropped cardigan or a longer duster. It closes with buttons rather than ties, which keeps the front flat and the silhouette clean.
Worth knowing
I like this one because the sizing trick is so simple: alter the yoke length and the number of shells, and the same recipe fits differently. No separate size charts to juggle. The chain-ring yoke is satisfying because it's honest — you can see exactly where the shell pattern begins and count your way to the right neck circumference. Working the button band on a smaller hook, after the airy body, is a nice change of pace; the fabric tightens up and buttonholes go in clean. And because sleeve length and hem length are yours to set, this jacket adjusts to a wardrobe rather than the other way around. It's the kind of make where the design does most of the fitting work for you.
Common mistakes
- Losing track of ring counts Mark every few rings as you chain the yoke; the odd-number rule is easy to lose across a long row.
- Uneven shell counts at separation Count shells from center on both fronts before placing markers, not just one side, so sleeves and body come out matched.
- Buttonholes spaced unevenly Mark the buttonhole points before working the buttonhole row, since chain-and-skip is hard to space evenly by eye alone.
- Skipping the fit checks Try the piece on at the neck, sleeve, and body stages; it's built to be measured against you as you go.

1. Foundation Yoke (Top-down)
For L-XL, 55cm Neck as Sample: Neck (start): ch2 (stretch foundation, left front)
Left Sleeve:
[ch4, dc in last ch]*1, then [ch3, dc in last ch] as many times as needed to reach 8.25cm (~7 rings, must be odd)
Back: ch2 (stretch), [ch4, dc]*1, [ch3, dc] to make 19cm (~19 rings, must be odd)
Right Sleeve: ch2 (stretch), [ch4, dc]*1, [ch3, dc] to reach 8.25cm (~7 rings, must be odd)
Final Stretch: ch2.
Check measurements for your size; for 2XL, reference the black sample (smaller neck opening but same approach).
2. Yoke Pattern
Pattern Row 1First Pattern Row Turn, ch3 (counts as dc). 2 dc into first ring. [For each ring except stretch points:] ch4, 5 dc in next ring (repeat for each subsequent ring). [At each stretch point:] ch5, 5 dc in next ring (Use stitch markers here to indicate raglan points). End: On last chain space, ch5, 3 dc in last chain.Mark all the ch5/shell spaces—they are your raglan increases.
Pattern Row 2Fan Rows Ch1, turn. Sc in first st. ch2, then in next shell space, work [(2 dc, ch2, 3 dc, ch2, 2 dc)] for stretches, or [(2 dc, ch2, 2 dc)] for regular. Always sc between shells with ch2 spacers. Continue, ending with sc in last st.
Pattern Row 3Shells Again Ch4 (counts as tr), turn. ch2. 5 dc in each ch2 space between fans (between dc2 and dc3 in large fans). For stretches: ch5 between shells. For others: ch4 between shells. End with ch2, tr in last st.
Pattern Row 4Repeat of Fan Ch4, turn. [(2 dc, ch2, 2 dc)] in each shell, or [(2 dc, ch2, 3 dc, ch2, 2 dc)] in stretch fan as before. sc, ch2 between each.Repeat Rows 1-4 until yoke is deep enough to separate sleeves and body.
3. Body & Sleeve Separation
When yoke reaches underarm (measure for your fit): Count shell patterns from center. Put markers.
Fold work so there’s an equal number of shells for both sleeves and body, with one for each front and remainder for back.
For underarm:
ch3, dc in 3, repeat to form a short chain/”rings” under the armpit (odd number; typically 3). Attach to other side.
Continue the established pattern for the body, skipping over the sleeves. Work as long as desired (sample: 25cm from armhole).
Finish body with shell row.
4. Button Band (Fronts)
With 2.5mm hook, join at front edge:
Row 1ch1, sc evenly along front edge.
Rows 2–3ch1, turn, sc in each st.
Row 4Buttonholes Mark 5 evenly spaced buttonhole points. Work “ch4, skip 4” at those points for buttonholes instead of 4 sc.
Rows 5–7ch1, turn, sc in each st (fill in buttonhole spaces). Edge (optional): Work 1 row of slip stitch through outer loop for neat finish.
5. Neckline
With 2.5mm hook, join at neckline, sc evenly.
Work 7 rows of sc, distribute increases (sc2 in stretches/2ch spots, sc3 in each ring).
Optionally, finish with a row of slip stitch through outer loop.
6. Hem
Attach yarn at one front hem corner.
Work [sc1, dc7 in next hole, sc1 in next, repeat] all the way around.
At corners or for curves, adjust as needed for symmetry.
Work a row of chains and sc as shown for straight edges.
7. Sleeves
Start at underarm center:
Continue working in fan pattern , mirroring yoke and reducing as needed (decrease by 1 shell in each decrease row until final width).
Aim for 7 pattern repeats long (or as desired).
End with same shell/hem pattern as body.
Assembly
Step 1Weave in all ends neatly.
Step 2Block gently for best shape and drape.
Step 3Sew a small square of dense sc fabric at base of button band inside if needed to prevent curling.
From the collection
Finishing
- Weave in every end left from the yoke rings, the button band rows, and the sleeve seams.
- Block the finished jacket gently so the shell pattern opens up and lies flat.
- Sew a small square of dense single crochet inside the base of the button band if the edge wants to curl.
Why it works
Each yoke section — left sleeve, back, right sleeve — opens with one wider ring before settling into narrower ones; that single ring marks the increase point for that side.
The button band is worked in rows, not rounds, because it only runs along the two front edges instead of the full circumference.
The underarm chain bridges the gap left by the separated sleeve and body sections, joining straight across to the other side rather than closing a full ring.
What it becomes
- A layering piece over a sleeveless summer top for cool evenings on a porch or patio.
- An open jacket to throw over a sundress for an outdoor market or garden visit.
- A lightweight cover-up for travel, since the cotton fiber packs small and breathes well.

FAQ
Can I make this jacket in a different size than the sample?
Yes. The sample is built around a 55cm neck circumference, and you customize the starting chain to change it. Altering the yoke length and shell count also shifts the overall fit.
Why does the button band use a smaller hook than the body?
The smaller hook is reserved for the neckline and button bands, while the larger hook does the main body. The tighter gauge keeps the band structured enough to hold buttonholes.
How do I know where to separate the sleeves from the body?
You measure the yoke until it reaches your underarm, then count shell patterns out from center. Markers placed there tell you where each sleeve and body section begins.
Do I need stitch markers for this pattern?
Yes, the notes recommend at least four, for the raglan and stretch points. They're what let you track the separation and increase rings as you work.
