My pants in-seam is usually 34 or 36. But 34 tends to be too short and 36 too long, and its very odd to find a 35 in-seam anywhere. It would cost what, $20 to have every pair of pants hemmed? I could do it with just the cost of some thread (and a few mistakes on donor pants).
Sewing can be very manly, life support troops in the USAF patch up parachutes all the time. Have any of the awesome gentleman of B&B's haberdashery ever hemmed pants?
Also, I think trying to sew my own tie would be a blast.
