Admin use different theme than users/visitors

Hey,

I’m wondering is it possible for admins of a WordPress to use and see a different theme than what the visitors see.

I say this because I am working on a new theme for my blog, but I want to work and edit it before I make it public for everyone to see.

I’ve tried editing the theme on my other blog, but there is too many things on my main blog (the one I want to edit the theme on) which I am using. So I can only do so much on a different blog editing the theme.

Hope this makes sense.

Thanks in advance.
