# Is it possible to use packages changepage and hanging together?

I'm trying to change the margins around some paragraphs with hanging indents, but LaTeX throws an error and doesn't really explain what's wrong. I'm a LaTeX newbie, so please forgive me if I'm making a simple mistake. Thanks for your help.

\documentclass[a4paper,11pt]{article}

\usepackage{fullpage}
\usepackage{hanging}
\usepackage{changepage}

%\setlength{\parindent}{0pt}
\setlength{\parskip}{16pt}

\begin{document}

\begin{hangparas}{.25in}{1}

\setlength{\parindent}{0in}

\textbf{One.}
\hspace{6pt}
Some text.  Some text.  Some text.  Some text.  Some text.  Some text.
Some text.  Some text.  Some text.  Some text.  Some text.  Some text.
Some text.

\textbf{Two.}
\hspace{6pt}
Some more text.  Some more text.  Some more text.  Some more text.  Some
more text.  Some more text.  Some more text.  Some more text.  Some more
text.  Some more text.  Some more text.

\end{hangparas}

\end{document}

No, you can't: adjustwidth uses a list environment, which sets \parshape, which takes over the parameters used by hanging. What precisely do you want to get? –  egreg Mar 8 '14 at 17:54
Thank you for the explanation. I just want paragraphs with hanging indents to have different left margins, moved into the page some. –  Casey Mar 8 '14 at 18:03
Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. –  Martin Schröder Mar 8 '14 at 18:04
Related question: How could I have found out myself that these two packages are incompatible? –  Casey Mar 8 '14 at 18:05

You need neither adjustwidth nor hangparas:

\documentclass[a4paper,11pt]{article}
\usepackage{lipsum}

\newenvironment{outpar}
{\par\setlength{\parindent}{-0.25in}}
{\par}

\begin{document}

\lipsum[1]

\begin{outpar}
Some text.  Some text.  Some text.  Some text.  Some text.  Some text.
Some text.  Some text.  Some text.  Some text.  Some text.  Some text.
Some text.


I removed the setting of \parskip because I consider it against good typography. In any case, 16pt is too much for any respectable document. ;-)
