Yes, this is a TAAT so may be deleted but I love the organisational discussions on here, so I'll kick off...
Don't iron (I haven't ironed anything for years. I still have friends).
Keep a present/card/wrapping box.
Scissors/lipbalm/handcream in every room.
More of an eco one, keep a bucket in the bathroom if you have a bath/shower and use the water as it's heating up to flush the loo/water plants etc.
Any others?
