I have an armslength kit that I'm trying to put together, but I have some questions and I can only reach David by snail mail, so I'm hoping someone who has completed the kit can help me out. The photocopies that came with the kit make it hard to determine just how the mouthpiece goes together. The directions say to round off the edges of the "1/2" ethafoam insert" with a razor blade. -- the only kit part that we have that could be that piece is a one-third slice of a yellow foam ball. Is that the part? It says not to trim it too much. How much is too much, or is it already trimmed?? Also, our directions came with two copies of the page on eyes, but no directions for a nose. Am I missing the nose page, or wasn't there one? I would appreciate any tips you can share! Cp
