I use a method quite similar to James’. Where we differ is that I harvest the whole stamen (anther and filament) and take it into my house. (In late May or later, even at 7:30 AM it can be too hot here to work comfortably outdoors.) Then I separate the anther from the filament and let the anther and pollen dry in place together. The following morning, I place the anther containing the pollen into the micro-centrifuge tube and store in a freezer. To use the pollen, I tap the edge of the opened tube to get one or two anthers into a small dish or cup, allow it to warm to outdoor temperature, then pick up an anther with a tweezers and use that to deliver the pollen to the flower and dab it on. There have been a few times that the pollen seems to dry to the anther and can't be transferred, but I’ve been successful with this method more often than not.
