These are hard to find in small quantities for home gardeners who want to save their own seeds. Glassine envelopes are the best choice for tiny seeds, which can stick to plastic bags or fall out of the corners of coin envelopes. These envelopes have a flap on the narrow end.
After filling the envelope with seeds, close the flap, then fold it over again and seal it with tape or an address label on which you can write the name of the seed variety. Or place the glassine envelope in a ziploc bag or paper envelope.
