I'm knitting a sweater back that has a rib and a sort of mini cable/twist pattern (see http://www.vintagepurls.net.nz/Downloads/NeedleworkIllustrated194.pdf).
The directions say I need to gradually increase the number of stitches from 133 to 153 by increasing one stitch each end of every 6th row. My question is: should the increase stitches continue the pattern (with its ribbing and mini cables)? For example, if the row pattern is K3, p2, k1, k into 2nd st. from the front, k into first st. and slip both sts. off together, p2, k3, would the increase in the first row (at either end) be done in a purl stitch? I'm not so worried about continuing a rib pattern but I don't know how to handle the cable or twist section. Any help is much appreciated!
