text: The thinner the thatch, the steeper the pitch, however there must be an adequate thickness of thatch over the fixings, thus a 100mm coat of thatch is steeper than a 300mm coat, but because the exposed stem length is longer (and therefore wears more quickly) and because there will be very little thatch over the fixings, the thatch will not last as long as a 300mm coat.
