I am trying to indent multiline footnotes 1.25cm after and including the second line. 

This is the code fragment that my template uses to set-up footnotes, which needs to be adapted:

```
\AtBeginDocument{% 
\renewcommand\@makefntext[1]{%
\parindent 12\p@ 
\noindent 
\mbox{\@makefnmark} #1}}

```

I found a general answer to a similar question by @egreg, as follows:

```
\makeatletter
\renewcommand\@makefntext[1]{\leftskip=2em\hskip-2em\@makefnmark#1}
\makeatother

```

However, while I can include this answer to my code fragment so that there is some indent, I can't get it to do what I want it to, i.e. indent 2.5 cm. Also, I am not entirely sure whether my code modification is right, since my try at merging the two code fragments was more or less a guesstimation. 

How do I modify my (the first) code fragment to keep the settings in principle, but add an indentation from the second line of 1.25cm using the method as described?
