Okay, let’s try this again…
The Book says, “A polo shirt placket is usually used on rugby-type knit shirts.” It goes on to say it’s similar to the continuous sleeve placket, and is “wider to accommodate buttons and buttonholes.”
Okay, first up, prepare your neckline by cutting an opening. It looks like I cut a V-shape, but really I just cut a straight slit. The knit just opened up like this. Also, I found it helpful to stay stitch across the bottom of the slit, as the knit kept stretching for me as I worked with it.
You’ll also need two facing pieces. One needs to be wider than the other, as it will become the placket as well as a facing. They should be about 1/2 inch longer than the neckline opening.
Lay them, right sides facing, on the garment. Match the straight edges of the facings with the neckline opening/slit. And just pretend that facing on the left doesn’t have a chunk out of it. I was working with scraps.
Sew 1/4 inch seam allowance along the straight edge of each facing. Only sew the length of the opening, leaving the last 1/2 inch of the facings unsewn
Flip the extended facing over at the seam line
And begin to pin your collar. The collar should be pinned at the center of what will become the placket on the facing.
This is where I was originally confused, so I’ll try to explain it as best I can. Where you just placed that pin/collar is the halfway point of the placket. So now you need to fold the facing over, with the fold line at the place where the placket will be. So if you’re making a one-inch placket, the pin will be 1/2 inch into the placket area, and the fold line 1/2 inch over from that. Fold the facing back to the wrong back so the wrong side is facing up again, and the placket is the fold line, NOT the seam (I know obvious, but it took me far too long to realize this…)
Now fold the other facing over at the seam.
And pin the other end of the collar about 3/4 inch away from the neckline (seam)
Flip the facing back over the pinned collar. Finish pinning the collar all around the neckline, pulling the facing edges up to match and get pinned, too
Sew all around the collar, catching all layers of fabric
See, that wasn’t so bad now, was it?!
