Thanks for the tip, great idea.
When I buy seed I save the package and refill and seal.I use the seed packages as book marks in favorite plant magazines and gardening books until time to recycle.

I save medicine bottles to store seeds in:)

Save my seeds in little coin envelopes but have traded for some that the folks made them out of left over wrapping paper and brown paper bags, reg paper that was folded to make a little pockets. Also at the craft stores they sell itty bitty plastic bags for around 1.29 for 100 of them.

I save all of the junk mail return envelopes for seeds. I actually use them for anything that needs an envelope but does not need to go in the US mail.

Great idea about the junk mail envelopes! I never would have thought of that.

Here's a website for seed envelope templates. I made them from scratch paper. :-)
