mdframed parchment layout

I have recently found a very nice example of how to create text boxes with a parchment-style layout:

http://www.texample.net/tikz/examples/framed-tikz/

Also, here on tex.stackexchange, there are numerous samples employing the framed package to produce this kind of layout.

However, in my document, I am already using the mdframed package to typeset a different kind of frame/box. Is it possible to produce such a layout using the mdframed package as well? If so - how?

Edit

I following the suggestion from Werner, I have played around a little and achieved the following:

\makeatletter
\usetikzlibrary{decorations.pathmorphing, patterns}
\renewrobustcmd*\mdf@tikzbox@tfl[1]{%three or four borders
\path(0,0)rectangle(\mdfboundingboxwidth,\mdfboundingboxheight);% replace \clip by \path
\begin{scope}[mdfcorners]%
\clip[preaction=mdfouterline]%
[postaction=mdfbackground]%
[postaction=mdfinnerline]#1;%
\end{scope}%
\path[mdfmiddleline,mdfcorners]#1;
}%
\newenvironment{parchment}[1][]{%
\mdfsetup{%
frametitlebackgroundcolor=none,
innermargin=5pt,
frametitleaboveskip=-\ht\strutbox,
frametitlebelowskip=-\ht\strutbox,
innertopmargin=10pt,
innerbottommargin=10pt,
tikzsetting={
line width=2pt,orange!30!black!10, decorate,
decoration={random steps, segment length=2.5cm, amplitude=1.5mm}
},
everyline=false
}
\ifstrempty{#1}{%
\mdfsetup{%
frametitle={\fcolorbox{black}{white}{Handout}},
}%
}{%
\mdfsetup{%
frametitle={\fcolorbox{black}{white}{Handout: #1}},
}%
}%
\begin{mdframed}[]
\relax%
}{\end{mdframed}}
\makeatother


However, when I use everyline=true instead of everyline=false, the pagebreaks in my document change. Can anybody explain?

Edit 2

I have finally found some time to revisit this issue. Please have a look at this MWE:

\documentclass{article}
\usepackage[a4paper]{geometry}
\usepackage{tikz}
\usepackage{etextools}
\usepackage[framemethod=tikz]{mdframed}
\usepackage{lipsum}
\usepackage{emerald}

\let\fancyfont\ECFAugie

\makeatletter
\usetikzlibrary{decorations.pathmorphing, patterns}
\renewrobustcmd*\mdf@tikzbox@tfl[1]{%three or four borders
\path(0,0)rectangle(\mdfboundingboxwidth,\mdfboundingboxheight);% replace \clip by \path
\begin{scope}[mdfcorners]%
\clip[preaction=mdfouterline]%
[postaction=mdfbackground]%
[postaction=mdfinnerline]#1;%
\end{scope}%
\path[mdfmiddleline,mdfcorners]#1;
}%
\newenvironment{parchment}[1][]{%
\mdfsetup{%
frametitlebackgroundcolor=none,
innermargin=5pt,
frametitleaboveskip=-\ht\strutbox,
frametitlebelowskip=-\ht\strutbox,
innertopmargin=10pt,
innerbottommargin=10pt,
tikzsetting={
line width=2pt,orange!30!black!10, decorate,
decoration={random steps, segment length=2.5cm, amplitude=1.5mm}
},
everyline=false
}
\ifstrempty{#1}{%
\mdfsetup{%
frametitle={\fcolorbox{black}{white}{Handout}},
}%
}{%
\mdfsetup{%
frametitle={\fcolorbox{black}{white}{Handout: #1}},
}%
}%
\begin{mdframed}[]
\relax%
}{\end{mdframed}}
\makeatother

\begin{document}
\begin{parchment}[Lorem ipsum]
\fancyfont
\lipsum[1-60]
\end{parchment}
\end{document}


Here's the list of issues that I would still like to resolve:

• The frame borders are sometimes "chopped off". I think this is related to the bounding box/clipping of TikZ, but I don't know how to resolve it.

• I would like to give the whole thing a background image that is cropped precisely to the drawn border.

Additionally, it would be great if the baselines could be slightly curved and tilted to look more like handwritten script - but I guess I can figure out how to do this - perhaps like this: Cthulhu document

There is an example that seems to be similar to what you're after listed in the mdframed documentation (Example 6). –  Werner Dec 8 '13 at 15:35
Carsten, did Werner's link help you resolve this, or are there still open issues? –  Paul Gessler Mar 31 '14 at 5:03
Paul, I finally found some time to revisit this. I've added the bunch of remaining issues to the original post (Edit 2). –  carsten Jun 12 '14 at 10:02
