in a nutshell: here we're going to try to make jewelry and stuff by building it with cardboard and superglue, sanding it down, and then varnishing it to strengthen and waterproof it.
i started doing this mainly because i wanted to make pretty elaborate-looking pendants and stuff but i didn't have access to materials that people usually use for this (like sculpey, terracotta, resin, metal, etc. I'VE NEVER EVEN SEEN A BOTTLE OF MOD PODGE IN MY LIFE. what is mod podge? it sounds wondrous). also, those materials tend to be quite expensive for me, so i tried making pendants with stuff that i already have.
(oh and BTW, sorry if some of the steps don't have proper photos :)) i always forget to document)
>>> cardboard (ideally illustration board and some folders)
i use illustration board for these because it's easily available here and it's very sturdy but easy to cut. in theory you can use chipboard too. the folders are for the details.
>>> cyanoacrylate superglue (like mighty bond)
the one i used is labeled "plastic varnish" and is used for wood. the lightest tint that i can get is "natural" and it's yellowish but unless you lay it on thickly it wouldn't matter
>>> sandpaper of different grits
>>> craft cutter (and lots of spare blades!)
>>> acrylic paint
>>> tiny paintbrushes
>>> other things you might find useful:
white glue (like elmer's)
a big jar
a sheet of carbon paper
a cutting board
>>> other things you might want to incorporate in the design, like:
chains or cords
