If you are aware of a post office which places the bar code further up on the envelope, then add more writing on the area of the envelope where you know the bar code occurs, but leave the writing on the bottom because that's where most post office sorters look for it.
And even when you're taking the non-machineable strategy, STILL always use the foam simply because "accidents" do happen.
Non-machineable rate still has thickness limits, so to avoid seeds lumping together in transit, this is how I pack the inside of the greeting card (see attached image).
Yes, I made the tiny envelopes myself and that part alone is labor intensive but it does use up scrap paper around here and I've created a template to make quick work of it.
You can find "coin envelopes" in the business supply area of a store like Walmart or Target in your area, and, of course, one like Staples. Just know that you'll need to use more than one of those for larger seed quantities (than First Class) to avoid lumps.
You'll still need to be able to fit the card in the envelope, too, so the envelope's limits are where your thickness limits are as well.
