drawing 3D leaf under SolidWorks

Hi everybody

Sorry about my english whish is not my native language.
I have to do a job under solidworks. I am not familiar with this software
and I don't have a lot of time to have the job done.
My problem is that I have to design "sorts of wings" (basics ones) and I
didn't found any help in the tutorial or in the manual.
In fact my wings are so easy to design that it woud be possible to do it
with simple operations.

For exemple I don't know how to add or substracts volums to eachothers
(except by extrusion).

If I creat a plane (with thickness) I don't know how to modify it to creat a
curvature (both directions)

For exemple if someone can give me clues to draw a leaf (it looks like what
I have to do) it would be perfect

I hope that my request was understandable

Thanks for any help
