So I found a new model today for the nudes. She was innocent, sweet, great body, the works. AAAND she wore black heels and matching undies! Perfect. She was awesome and the sketch turned out fabulous. Here is a rough pic (it's 5am, the lighting sucks)
Just tilt your screen. As I began to paint her... I got HIGHLY upset. The paper started to pill and get grainy and, as Daniel described it, looked "freckly". 
The problem was that I decided to buy a new brand of watercolor paper. I bought Strathmore 140lb cold press paper before, which I ADORED. But this time I bought Canson's 140lb cold press watercolor paper because
-it was 30 sheets for $20, while the Strathmore is $15 for 12 sheets
-I got over double what I got before
-times are HARD
The Strathmore is SO much thicker and heavier, although they are supposed to be the same weight and type. Well then, it shouldn't have gotten all bootleg when I attempted to paint on it. It's like it got pilled and frayed when I put water on the paper, even though it's WATERCOLOR PAPER.

Point is, go quality over quantity. If you have to splurge on the better quality, DO IT. Or else you'll be like me, re-drawing a perfect sketch at 4am that was ruined by paper of suckish quality.
