Contiguous Set-In Sleeve Construction
A modern hybrid construction that produces the tailored fit of a set-in sleeve in a top-down, seamless garment. Increases at four points create a set-in shoulder shape that is then transitioned smoothly into the sleeve cap.

How it differs from raglan
The shoulder section is shaped with paired increases at four points, but the increase rate slows as the shoulder progresses. This produces a curved shoulder shape (like a set-in sleeve) rather than the straight diagonal of a raglan.
Sleeve cap
Once the shoulder is complete, the sleeve cap is shaped with short rows that produce the domed cap of a traditional set-in sleeve. The cap is integrated into the body, not sewn in.

Why it is hard
The math is more complex than raglan construction. Designers usually provide row-by-row instructions for each size rather than asking knitters to calculate the cap shape themselves.
Best uses
Tailored fitted pullovers and cardigans. Garments where the relaxed silhouette of a raglan would not match the design goal. Sweaters knit in solid yarn (the contiguous shoulder is hard to combine with stranded colourwork).

Tips
- Follow the pattern row-by-row — the math is too complex to improvise.
- Use stitch markers at the four increase points and the cap transition.
- Try the sweater on at the cap transition to verify fit before continuing.
In depth
Contiguous set-in sleeve construction was developed in the 2010s as an answer to the tailoring limitations of top-down raglans. The technique combines the convenience of top-down knitting (try-on, adjust as you go) with the tailored fit of a traditional set-in sleeve sweater.
