How do I keep certain folders on my hard drive instead of iCloud for offline access?

My Documents file, like everything else, is automatically put into iCloud - and removed from my hard drive - meaning that I can't access it without internet service. I understand the benefits of iCloud, but I need access to my documents when internet is not available. How can I choose that at least certain folders remain on my hard drive? I have plenty of space for them. [I still use my Time Capsule, but I don't think it offers access from afar.]

Suggestions are most welcome!
