I've always done this.
Clothes, in the closet (when I've had enough clothes to do this, and thankfully I do again)
Go in this order, from Left to Right (I'm left handed):
short sleeve tops
long sleeve tops
sweaters
drapes/shrugs/boleros/cardigans (light over wear)
shapewear/corsets
skirts
trousers
dresses
then they must go from Left to Right
Dark colours to Light.
My books must be arranged by non-fiction education genera that flows into other subjects as naturally as possible
eg: biology> chem> physics> flowing into philosophy of science> epistemology> philosophy 101> philosophy of ethics> of politics> political history> history> archeology> anthropology> feminist anthropology> feminist theory> etc etc etc...
I shelve like I think: tangentially
Non-fiction? who keeps non-fiction??
I only have a small amount of it and so it all goes on one shelf together.
Hotdogs:
because of IBS - no mustard

no onions
Not because I don't love them but because they hurt, a lot.
