Since I'm currently at it here is a quick tutorial of how to make paper pockets to store your seeds.
They are easy to do and pretty much ideal for their purpose. No sticky tape or glue and no cutting or ripping to open them. Also, you can open and close them as often as you wish, no problem at all. If you want to sow all seeds at once you just unfold and have them all on a piece of paper before you. They're safe to store and to send in the mail in a simple envelope (no squashed seeds!).
