I punched some holes in the bottom of the Ikea plant pots with a hammer and nail for drainage, then (a trick my dad taught me) inserted a small square of window screen to prevent too much soil falling out the bottom holes.
Ikea sells plant tags you can label yourself. I’ve seen them in black, but if they only have blue or pink left, you can always spray paint them like I did. I used a metallic silver Sharpie to write the names of the herbs.
