Is there a way to show a max amount of items in jQuery Masonry?

We want to show max 12 items on http://denimjacket.nl/voorbeeld-pagina/,
so we would like to hide the rest. We can show max 12 items with a
Wordpress function, but ofcourse the Masonry will then only work on those
12 items, which is not correct. It has to work on all items, but still
show max 12 items.
