Plant Markers:
What do you use?
I use old mini blinds - I cut one end to a point - the other end - I round it off - the best I can.
I use a grease pencil / china markers and they have lasted for years.
The grease pencil doesn't fade like other pens and it can be rubbed with rubbing alcohol.
What do you use?

I use whatever I have - Popsicle sticks, writing on pot - and then I plant it outside and have no clue what the colours were supposed to be.
Using plant markers is my dream.
