Sabrina, here is what the packets and baggies look like. I prefer the paper envelope method because it lets me control the moisture levels of large numbers of seed easily and seems to prevent a lot of seed and sprout rot. I've noticed that any time live plant material sits directly against plastic, it tends to decompose. After an extended period of time (much more than 6 weeks) the envelopes sometimes will develop a little mold discoloration on them, but it doesn't seem to affect the seeds or sprouts.
These are dry because they are recently harvested. I stopped moist storage a couple of weeks ago, because I figure that 4-6 weeks from now, any tiny seedlings I set out may have problems if we have a cool, wet winter.
