Very cool puppets!  This is the style of shows we preformed when I worked with La Famille Marionettes.  No actual dialogue just music and short vignettes. I really love this type of puppetry because I think it breaks down language barriers. You can see the story through the music and action of the puppets. Thanks for sharing your videos with us.

Billy has a PDF file in his gallery that looks like maybe it is the output of the excel file but not the calculator itself. I don't think that Andrew has the excel file posted anymore.  I'll check my files to see if I have it.

That being said, more then likely for the market you are trying to hit it might not give you a price that would work for your area and the market you are trying to hit.  I am guessing off the top of my head that you are going to have to sell the puppets for under $25.00.  In fact if you could get them to under $20.00 in cost you are going to do even better. Don't forget that if you are going to sell them as toys they must be safe for the age group you specify.  No small parts that could come off and be swallowed.

This is the Muppet version of the song.

I really like the idea behind the Playing for Change organization.

The Playing For Change Foundation (PFCF) is dedicated to connecting the world through music by providing resources (including, but not limited to facilities, supplies, and educational programs) to musicians and their communities around the world.

I actually found the video because it was related to the Muppet version of the song.    Two very different takes on the song, both of witch I enjoyed.

The mixing of the PFCF version is just incredible. The fact that all those musicians where in different places where brought together in one cohesive piece is just astounding to me.  I was also moved by the fact that most seemed to be street performers.  I found the presentation very inspiring.

I agree with Na, that since you have specific questions that pertain to the UK that you might get more response at the UNIMA site. Hopefully our UK members well see this though and reply here.

Was searching for information on Sicilian rod marionette  and this site popped up on the results.  Not really anything about what I was looking for but a pretty nice overview of puppetry and the types.

Wow what an experience!   I bet your heart was racing a mile a min!  Happy to hear there was no extensive damage.

.... now tell the truth.... you had been wanting to remodel that room for years and your hubby would not let you.

That was great! 

I regards to searching for information, I think that Chris hit the nail on the head. Use the name of a puppeteer that you know used hand puppets.  Hand puppet would be the correct term for a Punch and Judy type puppet but as you are finding out the term had been bastardized. I think searching with the name of a puppeteer or even the name of a puppet like Punch and Judy well get you further.

Hazelle made a full line of hand puppets and they way they attached hands in the factory was with a rubber band.  Yep that is right a rubber band.  The fabric body of the puppet would be inside out and then the hand would be placed in the sleeve "backwards".  The a rubber band was placed around the end of the sleeve.  In the hands themselves at the "wrist" was a small groove that would help hold the rubber band in place.  Then the fabric body was turned inside out and you had a very finished connection.

The same concept could be used with Na's idea of gluing the hand on to the body.

Great logo LJ!  I have to ditto your plug for Titere, very good work for a reasonable price and in a timely fashion. Titere.... graphics designer to the puppets!

I followed the link to their blog and fond a post on ball joints.  While this is built in fimo and is a "doll" the concepts here could be used for a marionette or even rod puppets.  I was especially interested in the section on sculpting the hands since I always struggle with that. I am actually linking to part two of the article but you can back up two part one if you want.
