bags & backpacks

does anyone have a good portfolio/tutorials on bags & backpack sketching? i really havent done any softgoods, so examples would be real helpful

I have some examples in the softgoods section of my site:

A few people have been talking about doing some tutorials, will try to get someone (or myself) to do one.

in my portfolio link below I have some concept sketches for bags and backpacks
