Why the first tikz element is a bit off?

I've made a sheet of label using tikz. I am pretty happy about it but there is something that bothers me. The first row of label is a little bit of to the right compared to other rows and I don't know why.

Here is the code:

\documentclass{article}

\usepackage[a4paper]{geometry}
\geometry{bottom=2cm}
\usepackage{tikz}
\usepackage{fontspec}

\setmainfont{Sketch Nothing}

\usetikzlibrary{calc,decorations.pathmorphing,patterns}

\newcommand\myLabel[1]{
\begin{tikzpicture}[decorate]
% Outside of the label
\node[text width=7cm, text height=3cm](myLabel) {};
\draw[line width=1pt,line cap=rect,lightgray] (myLabel.north west) -| (myLabel.south east) -| (myLabel.north west) -- cycle;

% Text
\node[font=\fontsize{34}{25}\selectfont,align=center,darkgray]{#1};
\node[anchor=east,font=\fontsize{12}{16}\selectfont,align=center,darkgray] at ([xshift=-0.25cm,yshift=-2.75cm]myLabel.north east) {\year};
\end{tikzpicture}
}

\newcommand\myLabelRow[1]{
\myLabel{#1} \myLabel{#1}
}

\begin{document}
\pagenumbering{gobble}
\def \year{2017}

\noindent
\myLabelRow{Sureau}
\myLabelRow{Sureau}
\myLabelRow{Sureau}
\myLabel{Sureau} \myLabel{Cerise}
\myLabelRow{Abricot}
\myLabelRow{Abricot}
\myLabelRow{Mure}
\myLabelRow{Mure}
\myLabelRow{Tomate\\ verte}
\myLabelRow{Tomate\\ verte}
\myLabelRow{Rhubarbe\\ Fraise}
\myLabelRow{Rhubarbe\\ Fraise}
\myLabel{Rhubarbe\\ Fraise} \myLabel{Prunelle}
\myLabelRow{Prunelle}

\end{document}


Pay attention to the empty spaces inside your command definitions. If you remove them or suppress them with % comment markers, it works:

\newcommand\myLabel[1]{%
\begin{tikzpicture}[decorate]
% Outside of the label
\node[text width=7cm, text height=3cm](myLabel) {};
\draw[line width=1pt,line cap=rect,lightgray] (myLabel.north west) -| (myLabel.south east) -| (myLabel.north west) -- cycle;

% Text
\node[font=\fontsize{34}{25}\selectfont,align=center,darkgray]{#1};
\node[anchor=east,font=\fontsize{12}{16}\selectfont,align=center,darkgray] at ([xshift=-0.25cm,yshift=-2.75cm]myLabel.north east) {\year};
\end{tikzpicture}%
}

\newcommand\myLabelRow[1]{\myLabel{#1} \myLabel{#1}}

• You're stealing my favorite job of adding %! ;-) – egreg Sep 15 '17 at 20:58
• @egreg - you can have your job back if you promise to translate your LaTeX book into English. Deal? – Michael Palmer Sep 15 '17 at 21:12
• You'll have to continue chasing for missing %, I'm afraid. ;-) – egreg Sep 15 '17 at 21:29
