How can I make paper piecing patterns myself

if you posted a photo of what you might want to have paper peiced I think you would get alot of information on how to do it.

i would like to know how to paper piece a wilderness looking quilt

If you have never tried paper piecing, it might be difficult. If you have a quilting program such as Electric Quilt, it makes drafting a regular block or a paper piecing block a lot easier. If you can post a rough sketch it might help us to give you additional info. GOOD LUCK !!:)
