There is a product called Creative Paper Clay that you might want to give a try some day instead of Sculpey.  Instead having to bake it you simply let it air dry. You can use it over a form like you did with the Sculpey. In fact I sculpt over things like papermache' eggs you can get at the craft store or even styro foam. I made the heads for a set of hand puppets this way and did at least a start of a tutorial of how I did it here. You can also see examples of this process on my BlogTV account. All the heads in the Painting and Ball Joint videos where made this way. In fact the Ball Joint heads show the base I use.

Danny, these are things you'll learn about as you go. Eye placement is important because the direction of the eyeline helps the audience understand not just what the puppet is looking at, but also its emotions and reactions to things around it.

A little trick puppeteers use is to place the head at your own eyeline, or on par with how the audience will see it. Then you paint/attach/whatever the eye, and it should match up pretty well with how the puppet would be seen on stage.

There's an art to getting it right, and like I said in your case it's not bad (heck, it looks fantastic), it would just make for an unusual performance. Maybe the character can't see straight anyway? It has one eye after all...

Regarding stringing, I like the 9 lines vertical control. you can find a diagram, as well as a further information regarding marionette controls here:

I've decided to use cloth for the arms and legs, the arms are finished and attached actually, but my camera battery died before I got the picture. I'm still trying to work out the leg pattern though...

Looks great so far!

Really nice!

almost done! he just needs strings and a vest (I'm also considering a tiny hat.)

the pants/legs were trial and error, if I had known that this pair would work out I probably would have dyed them first, but I still may change them out later since I had pictured him with pants that had a little more poof.

know I just have to figure out what I'm going to use to make the control...

I love the shape and design of his body and hands! Very cool.  If you are going to cover the legs in cloths then the pattern for the legs can simply be a cloth tube that is stuffed with poly fill. You then sew two lines about 1/4 - 1/2 apart where you want the knee joint that does not have the poly fill in it.

Ahh... I should have looked at the second page before I posted the above. Looks like you figured out the pants part. I would still suggest putting the "tube" inside to act as the leg instead of relying on just the pants to tie the feet to the body.  Same thing with the arms. I make my "legs" as a tube as I said then at the top where I connect them coming out of the hips I have two wire U's that I loop each top of the tube over to attach the leg.  I also have a hip that is separate from the upper body that are attached together with fabric to allow the puppet to bend over more.

What you have now will work ok you just might not have as fine a control over his movements.  Since you are this far with him you might want to simply continue on and keep these things in mind for the next one.

great, he looks like a cyklop- genie!
