Well, no I'm not the Queen of Organizers but now and then I do come up with an idea that works.

I take a three ring binder (big one in my case, but you could use a bunch of smaller ones)

I get those plastic sleeves which have three holes in them and then I place my warranties, sales slip and user manual together in a sleeve.

I put them in alphabetic order, but you don't have to.

I keep the binder in a cupboard that is easily accessible. Then when something goes wrong, breaks down or what ever...there is the info on that item.

Even my DH patted my back on this one
