A daf with 2 mishnayot: 1. One who tattoos a tattoo is liable for lashes -- if the person both engraved in the skin and also added the ink. But maybe that's only if the tattooist wrote the Name of God. Or alternatively, the name of idolatry. Likewise, things that look like tattoos seems also to be at least taboo, even if they don't incur lashes. 2. Repeated violations of the same constraint on a nazir will incur multiple sets of lashes - or only one, depending on whether he was warned. The question arises with sha'atnez too - whether one is liable for one event or multiple events. And likewise kilayim - in terms of planting or plowing while mixing species.
