Which side of the watercolor paper should I use?
A rough surface can adsorb pigments better. Although both sides can draw, look at your personal hobbies, and if you like the smooth surface, draw on paper, it is cheaper
On the other hand, you can use it to draw a sketch, because the material of the paper is the same, the thickness is similar, of course, in fact, there are stripes, the surface sketch is better, I tried, but the cost is too high, not worthwhile.
The general paintings have stripes over there, and this kind of stripes is specially made to show the effect of watercolor.
