I'm fussy about tons of things but the list is pretty much equal in length to the list of things I really couldn't care less about, so it all balances out.
Some random excerpts from my Fussy List:
My outfits - tops, bottoms, shoes and accessories have to coordinate (also my underwear
)
My nail polish - has to be neutral or complementary to my clothes (I change it several times a week)
DH's pants - must be ironed with a proper crease
Pickles - must be products of Canada or the US (no pickles processed in India or China)
Home decor/decorator items - only what I've chosen and it must stay where I place it
The way food looks/is presented when I serve it to company
Never sleeping past 7:00 am under any circumstances (I feel so gross when I lie-in too long)
The colour of my car - I would walk before owning a white vehicle
