Hmmm. A web designer looking for above average free website templates. That really instills a lot of faith about your abilities as a designer. I guess the questions about looking for free WordPress themes may apply here also. Look at the link in my signature.
I'm looking for plain html and css templates to convert to joomla. It's a lot less work if you have the structure and css of a site to start with.
Sorry for the raspberry. My apologies. I guess I do that too, but I don't go to any free template sites. Usually the structure is FUBAR right from the start. Go right to the demos of premium sites and pluck the Html and CSS directly from them. Adapt some free textures and graphics elements to the site, and you are in business.
