### Hi again everyone!
Today, I've thrown together a video showing 4 methods I use to draw curves (in this case, a vaguely shoulder-like curve).

##### 1: Freehand
I wouldn't recommend this method, most of the time- a skilled artist can probably free-hand the line they want, but most of the time it's not the best way to do it. That said, if you're going for some styles, you almost have to free hand- though I would still say do a sketch on another layer, then free-hand on top of it, so you have a reference. 

##### 2: Additive Drawing
I figure this is a good name for it- you're essentially adding a bunch of lines together to form a curve. You should aim for something like [this](http://mathworld.wolfram.com/images/eps-gif/ParabolaEnvelope_950.gif) - a clean inside curve, and a bunch of lines protruding from the outside. Just erase the excess bits of line once you're happy with your curve. This is one of the methods I use most, and I consider it the best way to sketch out a shape- do a series of short lines which work together to make your curves, and clean it up as necessary.

##### 3: Subtractive Drawing
Sorta the opposite of additive, but somehow very similar- this is actually my favourite method. There are two ways to go about this. The one shown in the video is essentially additive drawing, but with way too many lines, and going a bit too far into the curve. The other method is freehanding the curve a bunch of times. Either way, you should end up with approximately the curve, drawn in a very thick line. Then, you use the erase tool to slowly carve away at the line until it's the desired thickness, and in the process you can shape it exactly. 

##### 4: Rounding
This one, I'll admit, is a lot like additive drawing. The reason I categorise it differently is that I use it differently. Like I mentioned before, additive is a good way to start off (picture a timelapse of a plant growing- it repeatedly moves in vaguely the right direction until it is the desired shape). Rounding is more for filling in a space- for instance, if you were drawing a person, and you drew the torso and the arm separately, this would be how I did the shoulder. You draw a very crude shape connecting the lines, then smooth it out as shown until you get it right. This can technically work for anything- you could draw a head by starting with a square and slowly rounding it- but I tend not to use it in most cases.

Now, two important things to note:
1. I am not a professional, and you should take everything here with a grain (or three) of salt. Consider it advice, not guidelines or rules.
2. Like with any tutorial, I'm super exaggerating all these processes. In reality, every single line I draw is some Frankensteined combination of those 4 methods, maybe even more- but categorising them like this can (hopefully) help people with less experience to do better curves.

Anyways, I hope you enjoyed this post, and more so, I hope you could take something from it! If you have any tips to share, feel free to leave them in the replies : )
