Shadow wraps don’t actually involve wrapping stitches, and that’s the biggest perk to this short row method. At the end of your short row, you knit into the stitch in the row below creating a “shadow” stitch behind the stitch next to it. This functions as your wrap, and it’s knit together with the stitch it’s behind like you would knit a wrap.
The concept seemed logical, and I thought I’d like this method, but I just don’t. Although the method is easy to work, this is the swatch I have the easiest time picking out of my pile of short row swatches because this technique feels kind of lumpy on the wrong side of the purlwise wraps. It’s also not an especially invisible way to create short rows. The stitch from the row below is pulled at a slight angle so the edges of the short row section are clearly defined.
