I'd like to make my own jeans...but I need help with, well, how

.
First I'd like to make a wide leg cut pair, second I'd attempt a bell bottom flare pant. I'd use typical denim fabric, make no back pockets, only regular front pockets (the little scoop kind). I just would like to know how to make a pattern and sew them (I'm sewing impaired), cuz I know how to run wild with creative embellishments!
Thanks for reading. ANY ideas or advice is appreciated!
