My recent Journey MOC, while quite basic, shows (I think) how the MUJI hole punch can be used in standard models, not just specific "Bricks and Paper" stand alone items:
All of the paper parts are held in place/together with LEGO parts, no tape/glue needed, even on the character. (For those wondering, there is a normal (armless) minifig torso and head under the paper on the character, with a few attached pieces to hold the paper in place) They were designed in Inkscape and printed as a PDF before being cut and punched.
I just played though Journey for the first time last night.
This is beautiful!. Well done!
