I declare that my attempt to make a mold and duplicate a particular shape an expensive failure. *sigh*

what is it you're trying to make, because it might be a balloon and plaster of paris/papier mache job.
I'll leave it that vague so you'll ask whuh?

It's a weird bent-arrow shape that's 3D, quite small, about the size of a finger but I need quite a lot of them. Because of it's shape I have to do a 2-part mold instead of a straight-forward one, too, and it's just too hard to do T___T

are you talking about like the finger things Vincent Valentine wears, because you can buy them
or alternately have you thought about using a bit of wood.
a piece of moulding will have a 45 degree angle on it and you can pick up a bit. this may sound odd but ask at a builder's merchants, explain that you want a finger sized piece of wood cut at 45 degrees, tell them you're happy to have scrap and don't be ashamed to tell them it's for an ART PROJECT FOR UNI (they are so much more helpful then)
you can pick that kind of thing up at any builder's merchants, I say that over something like B&Q because they tend to know what they're doing
My dad's a carpenter, I know more about wood than I care to.

It's not quite like that... I'm trying to do this. (just ignore the English there >_>) I've made the prototype, but my attempt in making the mold and casting it was a failure. I can't get the mold to not leak, for one =_=

when you make dollfie shoes they recommend using a paper cup to make the mold for the last.
you half fill the cup with the moulding agent, alginate, and insert the doll's foot, then top up.
then you remove the foot before the alginate is completely set and when it is you add whatever it is you're making the stuff out of (plaster)
alginate is cheap as anything, and comes in big boxes, so you can happily buy a set of paper cups and make as many of them as you need with one set of alginate. the paper cup won't leak and although the alginate should in theory just peel off (like a sock) it's my experience that it doesnt.

Sometimes being a dollfie owner does come in handy.

I still have some of the mold materials left here, I might try that again (otherwise it'll just sit and collect dust) and if I still cant work it out I'll go for alginate. Thanks for the advice!!!!
