Members don't see this ad.

so the pattern is being folded "into the plane of the paper".

I want to verify on this. is it being folded towards us the observer or the opposite/away from us ?

Away from us, into the paper/screen.

If you printed a problem with shades, cut it out, and folded it, the shades will always be on the outside.
