I have a Pinterest Board specifically for our Create a Free Web Site in WordPress.com at https://www.pinterest.com/katespinterestc/resources-for-creating-a-free-web-site-class/
In addition there are two boards on my business Pinterest which may be of help. While angled towards the resale industry, there’s a lot you too could use. Check out Your Resale Shop Web Site and Ideas for your Shop Blog.
Pinterest also makes a good search engine for your queries as well, and for those of us who are visually-oriented, can be much faster to sort through.
For a live example of a web site built solely on WordPress.com, visit the Historical Society of Sarasota County’s site.
