[Tex/LaTex] Two-column figure at beginning of appendix

Question

My two-column document has an Appendix, and I would like to put a two-column Figure at the beginning of the Appendix.

I tried to use the following code:

\documentclass[twocolumn]{article}
\usepackage{blindtext}
\begin{document}

\section{Section}
\blindtext[4]

\clearpage

\appendix
\section{Appendix}
\begin{figure*}[t]
A very wide figure that spans across two columns.
A very wide figure that spans across two columns.
A very wide figure that spans across two columns.
\caption{Figure}
\end{figure*}

\blindtext[4]

\end{document}

The result looks like this (The Figure was placed on the last page):

This question asks something similar, but it does not ask about the Appendix (or right after clearing the page). Also, the suggested solution with \twocolumn[...] does not seem to work in this case.

Answer 1

You can use the stfloats package:

\documentclass[twocolumn]{article}
\usepackage{blindtext}
\usepackage{stfloats}
\begin{document}

\section{Section}
\blindtext[4]

\clearpage

\begin{figure*}[!t]
A very wide figure that spans across two columns.
A very wide figure that spans across two columns.
A very wide figure that spans across two columns.
\caption{Figure}
\end{figure*}


\appendix
\section{Appendix}

\blindtext[4] \blindtext[4] 

\end{document}
