I noticed that a member of our community - BRB - uses Bristol board, and his drawings are so crisp and fresh. My question is which is the best type of board to use (vellum or smooth) and what exactly is the difference between the two
Bristol board is a heavier weight paper, and relatively expensive. If you mean to do pencil artwork and just pencil artwork, it's really not necessary - but it does have a superior permanence and presentability. If you are hard on your pencil drawings, do much erasing and aggressive smudging - bristol can take the punishment and hold up very well.
If your pencil drawings are meant to be the basis of a finished drawing in ink - this is where bristol has real utility. It can hold a fair amount of ink without warping, ink does not 'bleed' - and the paper is thick and tough enough to stand up to the abuse a dip pen can inflict on a paper surface.
The 'vellum' has a tooth to it, which is better for finished pencil drawing as it aids in using the graphite for purposes of blending and shading.
The 'smooth' has no tooth, which makes it better for ink techniques - no texture to interfere with the pulling of a smooth ink line.
Hope that helped.
