How do I add a blank line between the footnote line and the footnotes?

Between the footnote line and the first footnote on that page, I need to add a double-space. I've tried using the \ command, but it adds a space after the number. Does anyone know a way for me to do this?

What \documentclass are you using? Do you want to do this throughout your document, or just on an ad-hoc basis? – Werner Jun 11 '12 at 21:18
I'm using \documentclass[12pt, letterpaper]{article} and I wanna do it throughout the document. – bopgah Jun 11 '12 at 21:22

You can increase \skip\footins to make room, then redefine \footnoterule to put the extra space after the rule:

\documentclass{article}

\let\oldfootnoterule\footnoterule

\def\footnoterule{\vskip-20pt\oldfootnoterule \vskip20pt\relax}

\begin{document}

xxxx\footnote{aaa aa aa} xxxx\footnote{bb bb bb bb}

xxxx\footnote{cccc} xxxx\footnote{dddd}

\end{document}

You don't want to change \footskip, but \skip\footins. (Add \null\vfill immediately after \begin{document} to see why.) – lockstep Jun 11 '12 at 21:30
oops that's what I meant, thanks will fix.:-) – David Carlisle Jun 11 '12 at 21:34
Doing it the first way caused the footnote line to appear in the middle of the body of text. How do I change \skip\footins ? – bopgah Jun 11 '12 at 21:36
sorry I fixed the code in the answer. – David Carlisle Jun 11 '12 at 21:38
Something's still not right though. I think it's the "\addtolength{\skip\footins}20pt}" line. – bopgah Jun 11 '12 at 21:41
