We have a sort of wicker hamper for seeds inside, and an icecream box for seeds in the greenhouse...
So I always check the hamper first, then go to the GC for others, which of course, are already in the icecream box!
I might even become a proper nerd and write a list down on the PC, in a spreadsheet form, with dates, costs, etc., but there again, life's to short to stuff a mushroom...
