If you use the window blinds for tags, be sure to stick the writing underground, this way it does not fade away and all you need to do is pull it up to see what you planted.
This is our growing season in Florida.
I was wondering about that.. but I thought if you put the writing underground the moisture would also fade it off as well..
I would think burning it in is the best. Thats why I was thinking of user laser printed labels for my bags.
Use a black Sharpie pen, I have had the writing underground for over a year and could pull it up and still read it.
