Sleep, lovely sleep, what a concept!
Freshly returned, I am in similar throes - many irons in the fire, as it were. Lovely latchets are due to arrive Friday 29, to be tested and broken in. Assorted sewing projects sit in a waist high pile, awaiting my attention… we shall see what actually gets finished.
Glad you came to the conclusion to take the sleeves off for a waistcoat- you can always add them back on once you have more time. The mantua can be a bit fussy - pay attention to the fitting, whipping ahead of time or thoroughly pinning to test fit, and you will be fine.
