Thank you. I was inspired by @ecoinstant's amazing video. I can't live up to that video technique, but it did occur to me that I have been looking at those seeds every time I go to tend to the garden. It was a really pleasant experience collecting them in the early evening - I had forgotten how peaceful and absorbing so many of your contests are. I've stuffed the seeds in a Kilner jar for now. I have been recycling empty spice jars, but I'll start keeping them now.
It feels very good after the curtains have been cleaned, but a bit of an endurance test while you do them.
