Despite adjustments, the collar did not meet in the back. So I added a box pleat at center back, which worked great, but required the sleeves to be re-drafted. The sleeves could have had matching cuffs, until I discovered that the scrap of muslin I was using for the collar did not match the one on the sleeves! I had two different muslins in my sewing basket. The "tint" difference was quite noticeable in daylight, so off went the cuffs.
