As I merrily plow ahead with my Tangled Yoke, I thought I'd share one of the changes I made. The instructions, which are for a cardigan (I'm knitting this as a pullover), call for you to knit the entire piece (back and fronts) back and forth with a purl stitch running from the hem to the under arm to give the look of a seam. I did that, but wasn't sure I liked how it looked. So, in order to see if I would like it better without the faux seam, I undid it on one side. Here's what I mean.
First, here is a shot of the side "seam."

To remove it, I first dropped the purl stitch all the way down to the garter rib. (I wasn't going to undo the seam stitch there because it provides a focal point for the decreases.)

Then, using a crochet hook, I laddered the stitch back up -- turning it from a purl stitch to a knit stitch.

Without the seam stitch, the side looks like this:

I liked how that looked better, so before I joined the sleeves and body for the yoke, I undid the seam stitch on the other side as well. Important note: I conducted this experiment before I finished the garter rib on my first sleeve, so I could decide whether or not to add the seam stitch to the sleeve under arm. I wanted the sleeves and body to match, obviously.
I'm almost finished with the whole thing. If not tonight, then tomorrow.
