HI Polymerous,
What a wonderful idea to protect pollen if you can't get out early.
My family sometimes calles me the "Bag Lady". A couple of years ago I had double knee replacements and knew I wouldn't be out in the garden in time to collect all my DL seeds as they ripened. I found organza bags for a VERY reasonable price on Amazon and they have held up well. I was able to write the pod parent on my tag and tuck it inside the bag before I tightened it over the pod. When I got ready to harvest I just snipped the pod from the scape and threw the bag in a basket. Now worries about mixing up seeds as you collect them. You can't beat 50 bags for $3 with free shipping!
Here's a link to what I'm using:
