Making duvet with thickness and volume?

[xeonow]

Hello people, i have a question
maybe you can help me. iam trying to model a duvet for a scene. i do know how i can make a blanket, but i need a “thicker” one with kind of “volume” in it.
something like this:

I would work in a similar way to a pillow and pressure. but then don’t get any further if I want to make this crease. all tutorials i found in the www were talking about thin blankets or duvets without the crease. maybe you have any ideas i can do something similar in blender?

Why not try to create the regular blanket and extrude it out to thicken it. You might have to create to sections, then join them where it folds over. Once that’s done, do some sculpting for folds and creases.
