flat-felling the side-seams require
making sure you get it right the first
time.  i've had my fair share of bad
experiences -- i.e. edges over-fraying,
yadda, yadda...




not a good look.




then one day i meet mrs. rolled-hemmer
foot here on my last trip to hong kong.  
this baby sews a clean 3/16" flat-felled
seem and hem that turns any home-made
 shirt into a thing of awesomeness.
