Kingdom Hearts: Shrink Plastic Pumpkinhead Halloween Keyblade

27 October 2019

I have the *worst* luck with blind bags.

This’ a nice quality Kingdom Hearts keyring if you like Donald Duck (I don’t, really). In an attempt to make this look more like, well, something other than a mummified duck I decided to try putting some other stuff on the keyring with it.

Enter the shrink plastic. There’s some very clear images of these keyblades in the assets for the KH games and it’s not too hard to redraw them onto a piece of paper with a ruler, some careful measuring and a lot of maths. (except Oathkeeper. Oathkeeper’s a pain to draw, but that’s a story for another day). I tested a piece of shrink plastic with a ruler first so I know the stuff I’ve got shrinks by a scale of roughly 2.66.

The keyblade was drawn on clear shrink plastic (not the frosted stuff) with a black sharpie, and the silver/white bits done in Posca paint markers.

After shrinking I used clear embossing powder over the top to seal the pen; I’d read online that some varnishes make sharpie run and really struggled to figure out what would work. I tried two types of embossing powder. Both worked, but the Papermania one was easier to use as the crystals are finer so it’s easier to get a thin layer without them bouncing off all over the place. I don’t have a heat gun so I stuck it back in the oven until the powder melted. The thinner the layer is the more likely it’ll melt before the shrink plastic starts to curl back up again.

I wasn’t so lucky; it did curl up and I had some fun trying to flatten it back out again. It’s not perfectly flat, but it’s close enough.

Finally I made the pumpkin keychain out of Fimo polymer clay, with some black acrylic paint and gloss varnish.
