how can I make a thin surface out of a closed spline?

Select your sketch and then use the extrude feature. There is an option for thin feature. When you select this you can choose how thick you want your solid to be and what side of the line to be on. I can try to put a tutorial together later.
Here is a quick tutorial for you.
