I harvest the pollen sacs (usually early in the morning) and if they are not already open, they go under a light in the kitchen as they are allowed to dry. I haven't used post-it notes but I typically have a piece of paper with the name written on it and a small pile of pollen sacs drying. I can fit about 12 different flowers worth onto a single page.
When I come home from work I will write the name on the top of a centrifuge tube, place the sacs into the tube, then flick it a few times to liberate the pollen. I remove the sacs (this is easier than you would think) and place the tube in the freezer. Eventually I will print a batch of labels for the top of the tubes (green for tet and orange for dip) because I have had my fair share of writing disappear on me.
When I go to pollinate I will use a small toothpick with a flat end to collect some pollen and place it on the stigma.
