I've done a dozen or so baby sweaters without short rows, no problem. I did Jared Flood's Cobblestone a couple years ago and it turned out great. He includes short rows to lengthen the back and his are done in the yoke (after the body and sleeves are attached) and the wraps are done in the front near the upper left and upper right shoulders. I've been reading EZ's books and she suggests adding in short rows to lengthen the back - everything I've seen from her suggests putting them in while working on the body, before joining the sleeves (she may mention adding them in with the yoke but I haven't seen that yet). She also suggests wrapping and turning a few stitches before the "under-arm seam stitch", which is really not a seam stitch obviously. So although both Jared Flood and EZ are adding the short rows in the back, his are relatively long, come around to the front and are in the yoke, hers are relatively short, don't come around to the front, and are in the body before the sleeves join.
Any thoughts? Suggestions?
