You should they take each plant and hang it upside down in a dry, cool place in a paper bag for a couple of weeks to dry out fully. Seeds, along with the chaff and some debris, will fall into the bottom of the bag. This method ensures that you do not leave the seed heads too long and end up losing most of them in a strong breeze one day.

Winnow the seed by gently swirling the bowl and blowing air over the pile of seed and chaff. The lighter chaff will be separated and can be blown out of the bowl. If there is lots of dust in with the seed then you can shake it gently over a fine sieve. Continue to process until the seeds are left with very little other plant material. Once this is done then you can simply label and package the seeds and store them with any other seeds you have.
