Thank you! For a little while, I kept silica gel or "Drierite" in an open plastic envelope inside the jar. It tended to tip over, which was messy!
Now I like keeping the silica gel in a paper coin envelope, but you could also use half of a letter-sized envelope taped and maybe stapled closed.
I really like the "humidity cards" you can buy from ULINE or Driorite. They let you know when the desiccant is exhausted, or that you put in so much that the humidity goes below 20%.
You can fit a lot of 2x3" Ziplocs into one 3-pound peanut jar. Usually, within the jar, my 2x3 Ziplocs are grouped into 3x5 glassine envelopes, or bigger Ziplocs up to sandwich-bag size. Those fill up a 3-pound tub pretty fast.

I think it is important to keep the tightly-sealed jar size fairly small. Otherwise, every time you open it to take out one packet, you let in a large volume of humid air that exhausts the desiccant rather quickly.
