Once the pockets are done (see The Inseam Pocket Tutorial for how to do the pockets), the next time-consuming part is the neckline. I actually prefer to finish the neckline with bias tape, but, since we're making a bundle of these, all from different colors, it's easier to just cut facings than to try and match bias tape to each one. If you've got bias tape, and you'd rather use that, be my guest. :)
First, stay stitch the neckline edges (1/2" from the raw edge) of the garment front and back, and the front and back facings.
Then, stitch the garment front to back at the shoulders and the facings front to back at the shoulders. Finish the edges; serge them together or, if you don't have a serger, zig-zag the seam allowances individually.
Finish the outside edge of the facing.
If you serged the seam allowances together, press the facing shoulder seams to the front and the garment shoulder seams to the back (this will reduce bulk in the neckline seam). If you zig-zagged the edges, just press the seams open.
Press the back seam allowance (5/8", not counting any fringe...most of these were cut with the back edge on the selvedge, so no finish is necessary on the back seam) to the front, then pin the facing over it (the back edge of the facing should end up even with the fold...but these were cut rather in a hurry, so don't worry if you've got to fudge it a bit), right sides together, and sew it with a 5/8" seam.
Trim the facing seams to 1/4" and clip as necessary.
Turn the facing to the wrong side of the garment and press...the back neckline corner is finished, too!
Topstitch the facing down at 3/8"" from the edge. TIP: You'll get fewer bias wrinkles if you follow the curve of the neckline as you're topstitching, rather than pulling the seam out straight in front of your presser foot.
Doesn't that look nice? The last thing we do is put the closure on...that'll come later.
