<<never have had any success with frozen pollen>>

Seems different people do it different.

With this one there's a good chance that the light freezes have caused the
pollen to be sterile. Freeze it anyway and give it a chance.

I've had some takes from frozen pollen, mainly from Renown, and some failures.
Always note in the records if the pollen is frozen, but don't really keep a
record of the failures.  (if I went back I could tell)

As to your process, once the pollen fluffs, I only let it stay out for about
an hour before I put it in the envelope and into the freezer.

I've asked for help on this before, but for some reason, never have had
ny success with frozen pollen, so either there is something I'm
issing, the fall pollen I've collected just hasn't been any good, or my
reezer isn't keeping it cold enough.  Or the plants I've tried to use
t on just weren't receptive.
So, one more time.
I collect fresh, fertile looking fluffy pollen.
Store it for a day in low humidity room temperature to dry it out some,
nder a light bulb, on the unsticky part of a post-it note.
Is 24 hrs about right or should it dry longer or less?
Fold the post-it into a little envelope, stuck shut, and with a plastic
aper clip  just to make sure it doesn't unfold, put in a sealed baggie
r plastic tub full of powdered milk or other desiccant, then store it
n the (self-defrosting) freezer until needed.
Right?
Thanks in advance for any advice/comments.
