decrease/increase scarf pattern

[webbfamily]

I am thinking of making this scarf http://www.straw.com/cpy/patterns/sc...ue-zigzag.html
and I was wondering if I can increase and decrease with anyone of these techniques?

Yes you can, though if you use YO for an increase, it leaves a lacy hole which can be a nice effect, but there's no corresponding dec.
