neclaces

[xthinspirits.livejournal.com]

I KNOW this question/questions almost exactly like it have been asked before,
but I am still confused.
See, I'm wanting to make neclaces like these:

Anyway,
people have suggested shrinky-dinks, but I don't think those are what she uses- these just seem way too precise. 
People have also suggested using plexi-glass and a dremmel, different saws, or laser to cut it.
but the thing is, she makes them while on tour!
she says she wont mass-produce them, so you have to order them a few days before she gets to your city.
and im wondering how she makes neclaces using a LASER or dremmel on TOUR?
Maybe I'm just assuming that lasers and dremmels are hard to use / dangerous / not something you travel with?
Am i wrong? Maybe you actually can use lasers / dremels quite safely and easily on a tour bus?
But, for the sake of the fact that I can't use a laser irregardless if she does or not, does anyone else have any other suggestions to make these?
Thanks!!
