The weight of the paper has nothing to do with the paper tooth. It only shows how heavy or thick the paper is; the higher the weight, the thicker the paper. Index type card stock as for index cards is much more forgiving than paper, even when using markers.
Glossy card stock used for printing photos has a coating that makes it impossible to use with coloured pencils or pastels, but it’s brilliant with markers, inks and even watercolour (applied with a damp, not wet brush)!
Tooth: Think of little teeth on the paper surface biting off bits of colour from your pencil. When you look at paper with a magnifying class, you see little hills and valleys on the paper surface. It’s the hills that are called “tooth”.
The bigger the tooth, the rougher the paper surface, and the easier to colour with coloured pencils or pastels. – By the way, when referring to the paper surface, it’s only “tooth”, not “teeth”…as lovely as this idea may be… 😉
Construction paper is good both in weight and tooth, and even comes with different surface textures. The rough side of white Kraft paper is also great to use, but Kraft paper may turn yellowish over the years, especially when exposed to natural light.
In general, paper and card stock used for laser printers and photocopy machines is a lot smoother than for hand writing or drawing, that is the surface has little tooth and especially harder coloured pencils don’t colour well, not even with pressure.
For a start, drawing paper or hot-pressed (that is smooth) watercolour pads for use in school are good enough, later you can get artist’s quality drawing or watercolour paper. If you have an inkjet printer, you can cut the sheets to measure. Test what printer settings give the best results.
