How to Collect & Save Bachelor's Button Seeds

Since my interest in gardening lead to me collecting and saving seeds that I can distribute through my seed library I've been focusing more and more on old fashioned flowers. The "old lady" garden flowers I would have turned my nose up at a few years ago are now my obsession. Seeds for these flowers are easy to buy, trade, and most importantly: they're easy to save and share with new gardeners. One such flower is Bachelor's Button. Collecting and saving Bachelor's Button seeds is really easy.
