I was going through my art folders and came across this painting...I was struck by the pattern/design on it since it is so precise. This sort of thing would be easy in Photoshop, but in oils I have no clue as to how you'd do this. It looks like he painted the drapery first without the pattern, then somehow laid out the pattern on top in one value, and added a few lighting details on top. But how did he do this? I don't imagine it was drawn freehand since it is so perfect and the pattern doesn't distort/change as it wraps around the forms. Is there some way of masking out the pattern? A way to transfer the pattern?
Detail (haha, this is only like 60% zoom on the file, crazy hi-res, shame the forums won't let me post anything near that size):
