His sentence:
In blunt fact the operation itself, though prolonged, may not be violently dangerous, and though the technical preparation may be difficult, the actual surgery is of the most primitive type--simple extrication of an alien mass.
from Death Be Not Proud by John Gunther

Gunther uses commas and a dash to carry out the sentence and explain what it is talking about.

My sentence:
In the winter itself, though prolonged, may be cold, and though the money on heating will go up, the scenery is of the most beautiful ever--blankets of snow all the time.
