Logo design with TiKZ

Question

I'm working on a logo meant to evoke the old "Union Made" labels of the late nineteenth and early twentieth century (like this or this).

What I've got so far

How I got here

\documentclass[border=1mm]{standalone}
\usepackage{tikz}
\usepackage{fontspec}
\usepackage{graphicx}

\usetikzlibrary{decorations.text} % Allows us to wrap text around a circle

\setmainfont{Futura} % Historically appropriate

\begin{document}
    \begin{tikzpicture}

        % Draw double circle with text in the gap

        \draw [double distance=10mm,
               very thick,
               rotate=200,
               postaction={
                    decorate,
                    decoration={
                          raise=-1.4ex,
                          text along path, 
                          reverse path,
                          text align={left},
                          text={|\Huge|Newton Teachers Association 2017}
                    }
               }
            ] (0,0) circle (3cm);

        % Include "union made"

        \node[label=above:{\Huge UNION}] at (0,0.75) {};
        \node[label=below:{\Huge MADE}] at (0,-0.75) {};

        % Include clasped hands image

        \pgftext{\includegraphics[width=3cm]{Handshake2.png}} at (0pt,0pt);

    \end{tikzpicture}
\end{document}

Questions

1. I need to re-orient the year, so that it's centered (and right side up) at the bottom of the logo. (See the linked images above.) How can I do that? I tried adding a second decoration element, but that didn't work.
2. The circles are drawn as very thick, which AFAIK is the boldest line TiKZ has to offer, but they still look a little light for this purpose. Is there any way to embolden them further?

Answer 1

Please try to post examples everyone can compile. Your document requires a proprietary font and a personal image, even though neither is essential to the issue you want help with.

My example, in an attempt to 'look correctly wrong' follows suit. Even so, you won't be able to compile it, any more than I can compile your code.

You can use ultra thick or line width=90mm or whatever you desire. For the second decoration, you could use a preaction, but the white circle you're using will overwrite it. So, use a second \path.

\documentclass[border=10pt]{standalone}
\usepackage[T1]{fontenc}
\usepackage{tikz,gtamacfutura}
\usetikzlibrary{decorations.text} % Allows us to wrap text around a circle
\begin{document}
\begin{tikzpicture}
  \node {\includegraphics[width=3cm]{cauldron}};
  \draw [double distance=10mm,
  line width=2pt,
  postaction={
    decorate,
    decoration={
      raise=-1.4ex,
      text along path,
      text align={center},
      text={|\Huge\sffamily|Newton Teachers Association}
    },
  },
  ] (-90:30mm) arc (270:-90:3cm);
  \path [
    decorate,
    decoration={
      raise=-1.4ex,
      text along path,
      text align={center},
      text={|\Huge\sffamily|2017}
    },
  ] (180:30mm) arc (180:360:30mm) ;
  \node[label=above:{\Huge\sffamily UNION}] at (0,0.75) {};
  \node[label=below:{\Huge\sffamily MADE}] at (0,-0.75) {};
\end{tikzpicture}
\end{document}
