so am i supposed to wear the denim while it's still kind of damp to get definite fades from the start?
You can do that to help set your creases, but it's certainly not necessary. I never do it.
when denim is referred to as rigid denim does that mean its stiff
Yes, "rigid" means stiff.
I just ordered a pair of Denham Grader Virgin Japanese Selvage. Does anyone have any experiences with this brand? The look nice but if someone with firsthand experience can give me some info I would gladly appreciate it.
I have no firsthand experience with this brand. I read somewhere that they are a Dutch brand, but that's pretty much all I know about them.
