Chapped lips all weekend now have a little blister on bottom lip. It feels nothing like a cold sore. Is it just due to chapped lips? Contagious?

Assume cold sore. It is difficult to assess without an exam, but if it is painfull and you have a history of cold sores, you should avoid contact with other parts of your body, especially your eyes or anyone else until it is resolved. If the blister does not resolve or gets worse within a week, you should see your dentist for an exam.
