Lately I've been saving paper envelopes from bills. Even slit-open envelopes work well.
I can dry and even store seeds while air-dying in paper envelopes. If I fold and paper-clip the tops, they won't spill even if the cat knocks them over. And they take up less room than paper plates or paper bags.
By labeling the envelopes before you go outside to collect seeds, the seeds are only unlabelled while they're still on the plants.
If you collect big stalks or LOTS of flowerheads, you can drop the labelled envelope into a big paper bag or cardboard box before going outside so that the label is always with the seeds as soon as you harvest the stalks. Then, as seeds fall out of pods or you strip pods from stalks, you can store the reduced bulk in the envelopes so they are less likely to get stuck in flaps at the bottom of the paper bags or boxes.
You can cut a cereal box or box of crackers in half lengthwise if you tape the open flaps closed first, with packing tape. Then you get two trays that will each hold 3-9 paper envelopes upright. Then they take up so little room that you can store as many varieties of seed as you want to, in a small space, even while they are still drying.
