Answer 1

Just grab some picture that has an appropriate size and use the background package to insert it into the background of your document:

\documentclass{article}
\usepackage{background}
\backgroundsetup{
    angle=0,
    scale=1,
    contents={\includegraphics[width=\paperwidth, height=\paperheight]{paper-bg}}
}

\usepackage{lipsum} % to print some random text

\begin{document}

\lipsum

\end{document}
