Watercolor on Arches
The question arose after yesterday's post. What is Arches? D'Arches or Arches, in "art speak," is the benchmark watercolor paper. It's handmade, French paper consisting of 100% cotton fiber, and made in three textures: rough, cold pressed (some tooth) or hot pressed (smooth). It also comes in different weights: 90#, 140#, 300# and 450#. Pound weight is based on the weight of 100 sheets of 22" x 30" paper. The thinner sheets weigh only 90 pounds, and so on.
