This is the simplest little "no muss/no fuss, hardly any tape" origami envelope. YOu can make them small or bigger depending on the square size of paper you cut. You fold as shown, and then open up the top "flap" where you put the seeds into the "envelope" and fold down, and I put my seed label on the back there to use to hold it all closed - NO tape.
I make these when I have time :D
