Rolled Hem

I used my new rolled-hem presser foot for my Bernina Artista 180 for the first time yesterday.  I've had a couple different sizes of rolled-hem feet for my older Bernina 830 Record since I got it, back in 1978, and used them all the time; so I've missed not having one for my newer machine.  Either I switched to the other machine to put in a rolled hem, or I rolled it with my fingers, which was a bit imprecise.  Finally... I got one.  This one is a 4mm rolled hem.  And here's the reason I haven't gotten one until now:  that thing cost $45.95!!!  :-O  But... I wanted the hems on these wedding dresses perfect.  And perfect they are.  Just take a look at this hem, inside and out:
