I have a jar with IKEA bits and bobs in and a couple of jars with various screws etc in. They live in the shed, by the toolbox.
I have regular chuck outs, I don't hoard anything really. I have books, records, CDs etc. I know where my birth cert and other bits of ID are. I have a draw with random electrical bits and bobs in - charger leads, spare co-ax, plugs, fuses, insulating tape and sensible stuff. A 'useful' drawer, where batteries, torches, radiator key, passport, instruction books for the boiler etc live.
No clutter, nick-knacks or ornaments really. I don't have a flower vase even. I use a large kilner jar if I ever need one. I can't be doing with stuff everywhere. My parents had overflowing cupboards of stuff. When Hubster moved, he took everything that he needed. I've not binned anything that he's left behind (2 bikes for a start) as I'm not like that. There isn't much of his here. He will get around to taking it and sorting out somewhere for the bikes too.
