Or… add a loop within the loop, but loop the loop sounds much cooler.

 if (have_posts()) : 
 
while (have_posts()) : the_post(); // the post loop$temp_query = $wp_query;  // store it
$args = array( 
'paged' => $paged, // paginates
'post_type'=>'post',
'posts_per_page' => 3,
'order' => 'DESC' 
); 
$wp_query = new WP_Query($args); 
 
while ($wp_query->have_posts()) : $wp_query->the_post(); 
// -- your new loop -- //>endwhile; 
 
if (isset($wp_query)) {$wp_query = $temp_query;} // restore loop
>endwhile; 
 
endif;
