There is a resurgence of circular yokes on the runways and market at the moment. My previous post discussed some of the considerations in knitting them. For those not up to working that particular way, there are variation in carrying the patterns around the body in “continuous” lines.
If raglan shaping is used, angular lines are created where patterns meet. All knit is essentially vertical striping. Raglan shaping should match both front and back of sleeve, the wider the raglan shape, the less sharp the stripe intersection. Striping in a traditional cap sleeve creates designs that move horizontally across combined body and arm at rest.
When designing a sweater with a shaped sleeve cap, knit a sample of your stripe pattern. An online stripe generator can help visualize stripe formulas, color ways, etc. If knitting fair isle use row counts for FI pattern height for stripe placement. It is helpful to have a 1 row, 1 stitch graph to plot repeats out. It does not matter if the grid is square or rectangular, providing that vertical and horizontal numbers are based on your gauge. Draw a line from armhole point to armhole on both pattern and sleeve, and there is your match. Work stripe pattern up from armhole line for your cap, down from line for sleeve repeats.
In my theoretical sweaters the sleeve’s wrist edge is technically below the armhole to waistline length, so stripes need to be plotted accordingly, from armhole down. The same method is used if single motifs or other variations in striping are involved. For single motifs, if matching them in body and sleeve cap, begin by designing them so they fit in the cap’s crown. Place motif in body and sleeve on same line, and plan the remainder of the sweater calculating from the armhole as for stripes, basing placement on numbers of rows in each design segment.
