Couturier is a small utility for merging multiple PDF documents and images into one document.
Drag and drop .pdf’s, images onto the main Couturier window, give the document a name, encrypt it if you so wish and hit ‘Combine’. A flawlessly usable application that does what it’s supposed to and not a jot more or less.
Annoyingly the application hasn’t been updated for a while and as such the .deb file provided is intended for Ubuntu 9.10. Good news, however, is that it installs fine on both Ubuntu 10.04 and Ubuntu 10.10 (however you will need to install gnome-sharp2) (this link uses apt-url to install this from your repositories.)

After downloading double click on the .deb file and choose "open". This will open the installation manager. After the program 's been installed, look for it in the "office" entry in your Gnome menu.
The programm works pretty straightforward. Give your new file a name, choos a location to sav is and select the files you want to combine. That's all.
I combined three large pdf files and it all worked perfectly.
