| Once people learned to use needles, of course they used those, but I am sure that before that, among other things, rose thorns were used. You only have to find the right kind - strong and very sharp. It is also cool that they come with a readymade handle - part of the stem. | ![]() |
The technique is naturally the same as with needles - you dip the thorn in some colour, and punctures the skin.
