Stephen Quiller is a well known watercolor artist who puts his name to fine artist's supplies. Here is his brand of 140lb 100% cotton cold press paper for your use as a watercolorist. This is a block of 12 sheets of 11X15 paper. If you haven't used a block before, this is glued together on all four sides. Most of the time, watercolorists either have to deal with stretching 140lb paper or deal with the paper buckling from the uneven distribution of watercolor paint across the surface. With a block, you don't have to worry about buckling; the paper will stay flat. After you finish and dry your painting, you can then remove it from the block using a nail file or similar flat object. Cold press paper is preferred by the vast majority or watercolor artists. Cold press has a texture and tooth providing a surface that is just right for most work.
