Like JayG I also use an old shoebox.  No need to stuff paper down the side of it - more seed packets go sideways down it.  There's no organisation in it though ... perhaps I should learn from you lot and try!

I've got a large Brooke-Bond tea tin for most of my seeds.

The kilo boxes of pea seed are a different matter though!

I found the organization helps. Otherwise, things I'm sure I have several packets of turn out to contain one or none, and vice versa. It also encourages me not to leave seed packets around the house because they tend to go for very long walkabouts    Just find the correct tab and shove the packet in place. Done.
