I would love to start making latex puppets (such as kira from the dark crystal), and I don't really know too much about that.Would someone point me in the right direction? suggestions on materials, sites, or tutorials?

Welcome to Puppets and Stuff!  May I ask what experience you may have in the arts?  The reason I ask is because in order to create latex puppets you need to be able to sculpt.  If you have never worked with any type of clays and sculpting them then you might want to explore that area before you dive into the rest.

There really is not any cut and dry information available on making latex puppets but the process is similar to that of making latex mask. Here are the results to a Google Search: Google search that will help out some. It at least gives you an idea of what you are in store for. Below is a sampler video of a DVD you can get from artmolds.com on mask making.

If you watch the video at YouTube you'll see a lot of other suggestions for videos on the subject.

I'm pretty sure that Kira is made out of a kind of injection rubber that cures in an oven, a method which is probably out of your reach.  But there's an excellent method that Noreen Young uses where you sculpt a positive from plasticine, take a mould of that with plaster of paris, and then do a multi-layer slush cast of your mould with the liquid latex available at art stores.  Unfortunately, it seems that Noreen no longer sells her DVD instructional video on this method now that she's the art director of the Puppets Up! festival in Altmonte, but it didn't seem too difficult to me.  She always made a big flat space on her heads, either the base of a wide neck or a truncated head so that she didn't have to do a keyed mould, and in the case of the head would fill it in later on with a carved piece of foam rubber.  She added acrylic paint to the foam-rubber to act as a base colour, and then painted on top of that with more acrylic paint and makeup fixitive like spirit gum.  The result was a little tacky, so she dusted the finished product with talcum powder.
There's a little to start with.  I'm sure that someone here is more qualified to answer your questions than I, though it's hard to show anything without actually being there.  Perhaps you could find some used copy of Noreen's video, or check local resources?

Abdolos is correct that Kira was not just plain latex. Pretty sure she was foamed latex.  I thought I would add a few other links here on the subject. These are companies that sell supplies since that is normally the next question that comes up.

You might notice that they are both makeup supply companies.

I'm fairly experienced in sculpture, particularly oil based clay(modeling clay). I'm comfortable using them as well. I appreciate the input. I thought about making a replica Kira for my first puppet, but I also have many of my own designs I'd love to try as well. I like the way the material she's made of looks, so thank you again for telling me what material she was actually casted in.
I wish I was able to post some of my other work so you could get a better feel for my abilities. I feel that with the experince I have in sculpture that the actual sculpting of the head and face would be the least of my problems...
How would I put hair on a foam latex puppte head?
how would I make realistic eyes for the puppet, or buy them?

Welcome to Puppets and stuff.

If you sculpt in the oil based clays then you are on the road already.

Hair on a foam latex puppet can be done in several ways. You can use pretty much any method you see here for hair on a regular sheet foam puppet. That would include a wig, fake fur, yarn etc. You can even set hair into the foam latex with a punch. http://puppetsandstuff.com/community/index.php/topic,4454.0.html

Yep you can make your own eyes if you want, there are tons of methods out there for this, or you can buy them pre made.  Most doll suppliers have these types of eyes. You'll find a lot of tutorials on this out there if you Google Search: google but I did just find this one just now I thought was interesting. http://www.nonidolls.com/eye.html  Instead of casting them they are using something like Sculpy or Fimo.

Thanks! how is foam latex mixed? I looked up the product, and there are a few difrent components mixed in. I was a little conserned about how much of each you have to use, and how to determine that.

That I can't answer since I have never used it. Normally though when you purchase such products they give you the ratios that you are supposed to use.

I bought foam latex already mixed in a pail from any special effects copmpany. I got mine hear
