Going absolutely bonkers over here trying to find a suitable spherical mold that ships from the US.
I need an actual sphere, no flat sides. Am I just better off attempting to make my own mold, or am I being dense and not looking in the right places?!

Do you want a sphere mold or a hemisphere mold?  And what size?

A full sphere, and either a one or two-piece mold is totally fine (though I think I would *prefer* a single piece).
Eventually looking for multiple sizes from about 1"- 3". Around 2" is where I'd like to start.

A hemisphere mold could be made from various materials (some of which might require a release), but a fully spherical "mold" could only be made from something like latex rubber, or several-step rubber processes.

Check out some of these links for hemisphere molds (sometimes called "ball" molds because they can be used to make 2 halves for balls), or they may be called 2-part molds or split molds:

I recently started working with resin, and am loving every bit of it. 

My favorite molds are silicone molds. Target dollar spot usually has cute ones for a dollar.  Right now I think they have pixelated hearts, lightning bolts and dollar signs.  You don't need mold release or anything, and they are easy to pop out.

What I have found to be really helpful:
 wooden craft sticks.  (I got a decent sized bag at wal-mart in the craft section for about 2 bucks.  You can reuse them until they get too gunky, or i usually leave them wet on a paper towel, and its time for a new one)
Plastic cups.
silicone molds.

I also use the envirotex lite resin.  I just to two cap fulls, each time, and they makes out 6 or 7 pendants.

I feel like i'm getting a little jumbled here, i'll stop while i'm ahead.  Message me if you any questions!

Have you thought about making your own mold from a spherical form?

I have, yes. Smiley I've never made a mold, so I'm just looking for an alternative at the moment. I know it's kind of a tricky thing to get right. I'll look into the two part option some more. Thanks everyone!

There are different kinds of resin, and the 2 main kinds are intended either for deep molds or for shallow molds and coatings.  And one "tweaked" epoxy resin (Easy Cast) can be used for both but has some disadvantages after curing.

You can read a lot about the kinds and how they can/should be used, as well as molds you can use or molds you can make to use with resin, plus much more, in my previous YahooAnswers here (which also include a link to the page at my site on resins):

No matter if you purchase a mold or make your own, you're going to end up with a flat area where the resin is poured into it. If you get 2 hemispheres, you'll have to fuse them together...or if you get 1 single sphere, there has to be an area where the resin is poured into the piece which will need to be sanded/buffed down to make it smooth. Know what I mean?

Sigh- I purchased a medium size bottle of EnviroTex Lite resin, a month ago (I did checked, the harder was clear according to my eyes), fast forward a month, now it is a little bit yellow. If I go ahead and mix a batch, will it come out yellow or clear? Help!  Huh
