I apologize for "pimping my blog", but this is easier than drying seeds on paper plates, and takes up less space.
The only trick is that FILLING an envelope with wet seeds and moist green plant parts encourages mold unless you can create a THIN layer of seeds, and/or shake them several times per day until they are mostly-air-dry.
