Attachable label for seedlings and pot plants

For my balcony, i grow some tomato seedlings. Because they all look very similar to each other as long as they are small, i would like to label them.
I use plant pots witch i make out of old newspaper. And for this pots i have made this labels.

Post-Printing

Glue the labels to the printed part
The labels don't stick very well to the printed surface.
But i get very good adhesion if i glue the label with a glue stick to the part.
