The invisible raglan increase is perfect for seamless top-down sweaters. The raglan stitch is flanked by mirrored increase stitches and the raglan seam has no holes. Whether the sweater is worked in stockinette for another stitch pattern, the seam will be virtually invisible and the patterns will match perfectly.
