So here you go, this is what I did this weekend:
I got the sleeves actually ATTACHED to the jacket! Yeah! This actually may be done by the time the snow flies. I am getting the itch to sew some summer clothes so I have to finish this soon. If I put it aside, it won't EVER be done. I've done that to projects before.
The sleeve were actually quite easy to attach. The wool melton was great to ease into the armhole. I've only set in sleeves a few times before so I was nervous about this. I must have been using difficult fabrics before, because this was a breeze. I just followed the directions in my tailoring book and all was well. You will notice if you look at the sleeves some vertical lines in the sleeve cap. I have not put the sleeve heads in yet. I am thinking(hoping) that that will solve the problem. Could also be the dummy, her arms stick out a bit. I did baste in horizontal and vertical lines to hang the sleeve so I know it it not skewed. We'll see I suppose.
Here is the armhole from the inside. I pressed the seam allowances between the notches into the sleeve. Below the notches, I cut to the staystitching every 3/4" and pressed seam open, then hand stitched the seam allowance under the arms back onto itself so it would stay tidy. This is supposed to give me more room in the armhole.
Note all the stitching on the back of the armhole. There are 3 rows here and 4 underneath the arm hole. There is one row just on the body of coat(2 underneath the notches) for staystitching. I used this in place of taping the armhole. I was worried about bulk with a 4 layer seam already. The other 2 rows are the actual joining of arm and body. Had to go around twice, didn't stitch quite deep enough the first time and the staystitching showed on the outside.
