This question is mainly for Liesl, but please feel free to chime in! I've been sewing lots of sleeves this fall, and noticed that about half call for being set "in the round" (i.e. side seams sewn first) and half are inserted flat (before sewing the side seams). I find the flat method infinitely easier, especially when working on itty-bitty sleeves that don't fit around my machine's free arm. Liesl, how do you decide which method to use for a particular pattern? Do you find that one is more comfortable than the other?
This is mostly idle curiosity, but I did change the order of construction on a school days jacket last night so I could set the sleeves in flat, and I need to know if the sewing police are coming after me.
