I am writing a math work, and I'd like to create a background which looks like a math notebook. Any idea how to do it ?

I found this solution, but I don't know how to put it in a mini-page ...

%%%
%%% quarre Kaestchenmuster
%%%
\def\quarre{%
\raisebox{\footskip}[0pt][0pt]{%
\

setlength{\unitlength}{.01\textwidth}% Einheit_1/100_Textweite
\begin{picture}(100,115)%
\color{black!10}%
\linethickness{0.075mm}%
\multiput(2,0)(2,0){49}{\line(0,1){110}}% 110-VER
\multiput(0,2)(0,2){54}{\line(1,0){100}}% 54-HOR
\color{black}%
\put(1,112.1){%
\begin{footnotesize}
\textsl{\textbf{Notizen}}
\end{footnotesize}}%
\end{picture}%
}%
}


would be great to combine it with this:
Background image for minipage


Question: How much of the English language comes from each of its influences?
Answer: The question is: Is the English language a Germanic or Romance language, and what criteria will you use to determine the answer? One could argue that the History of England is similar to that of. the other five Romance languages in that the Romans conquered France, Spain, Portugal, Romania, and Italy. The presence of the Romans in England lasted approx. 400 years. Then the French invaded and they added many new words. The scientific revolution added also. Therefore, if the preponderance of the words are derived from Latin and uses the above comments, the conclusion is: that English is a Romance language.
