The piece of paper is about as trivial to model as you might thing. I decided to UV Map it so that I could have both a front and back side of the page (though you can’t see it here). It also means that the stuff on the page itself will deform properly if I decide to wrinkle or otherwise mess with the page.
The pen was trickier to model than I thought. There are some funny curves and you have to cinch the subdivision surfaces at the right places for them to look right. For some reason the label that I applied to the pen refuses to show up in this rendering. I’ll have to dig into that later.
