Here are a couple of suggestions for those of you new to sending and rsceiving seeds
You can re-use the bubble envelopes that you receive in the mail. Just place a new address label over your name and address. remove the old stamps or mark through them and add new postage. Those envelopes can be reused time and time again. So save them in a shoe box or someplace handy so you can find them when you need them
Unless I can find a good deal on small envelopes, I sometimes buy large ones and cute them into 4 smaller envelops which works out to 25 or 30 cents an envelop. I staple the cut sides and put a strip of tape over the stapled edges to enclose the staple on both sides and then seal the last side after the seeds are inserted.
If you want to get really creative, you can make your own seed packets. There are several places online that have free templates. Here is a link to one that has lots of templates that you can copy and print out
