Sleeves are always one of those easy things to assemble, but if I haven’t done them in advance, can slow down assembling the coat.

I first cut the sleeves (see above left) in Alcantara. Notice the marks for sleeve apex and three parallel lines for the sleeve head formation. I also cut the lining using pinking sheers, which proved to be a sucessful exercise on the test coat (see above right).
Firstly I stitch the longer back seam and press it flat, but with all of the seam allowance folded towards the front of the sleeve. I then topstitch the seam, within 1 to 1.5mm away from the edge. The sleeve is then closed off by sewing the front seam, which is just conventionally pressed flat.
I am using the slightly adjusted pattern I did for the calico coat, which is designed to give a more roomy fit at the back, while still being quite tailored at the front.

These two photographs show what I mean: (left) you can see the sleeve is set in cleanly and is well fitted (right) you can see a series of puckers at the seam, which is giving it a fuller fit. To mimic this I need to adjust the level of gathering in the sleeve head so it is smooth at the front and across the apex of the sleeve, but allowing it to pucker slightly as it falls down the back of the sleeve.
