I have totally gone retro old-school with a cheapo embossing label maker. By hand.
If the color ever washes away, the raised text will still be easy to see as a backup.
Plus, it is fun seeing the labels look so old fashioned.
The adhesive labels then get stuck onto metal plant markers.
Currently less than $10, including labels and embosser.
