There is an artist sketch from about 200-300 AD, if memory serves me, that contains a triangle of holes in the facsimile sketch exactly where they are in reality.

Are you perhaps thinking of the Hungarian Pray Codex from the 12-13th Century with the four poker holes? The triangular patches came from the fire of 1532 when molten silver from the casket it was stored in burned through one multiple folded corner of the Shroud. The so-called poker holes predate all of that. The provenance of the Hungarian Pray Codex shows the Shroud and it has a reliable dating prior to the Shroud appearing in Lirey France.
