In my preamble I define the following, which allows me to do this  
automatically:

\newcounter{last}
\newcommand{\interrupt}{\setcounter{last}{\value{enumi}}\end{enumerate}}
\newcommand{\continue}{\begin{enumerate}\setcounter{enumi}{\value 
{last}}}

Usage is clear: interrupt the list with \interrupt, and continue it  
with \continue. In the middle you can put almost anything you like,  
you can change section and even include another independent  
"enumerate" environment! The drawback is that this does work only for  
"first level" lists (as it uses the "enumi" counter).

I find this mechanism especially useful when used together with the  
"enumerate" package; you have to modify \continue in the following way:

\newcommand{\continue}[1][1.]{\begin{enumerate}[#1]\setcounter{enumi} 
{\value{last}}}

In this way, a specially formatted list, such as e.g. a list of  
special conditions labelled as (C1) , (C2) , etc., can be "continued"  
throughout the whole paper or book, just by starting with \begin 
{enumerate}[(C1)], interrupting with \interrupt, and continuing with  
\continue[(C1)] ... and finally ending it with \end{enumerate}.

This suits my needs. Hope it may suit yours,
