Spotting the difference between formal and informal fallacies

I know the theoretical difference between the two (error in logical form vs error in content/expression) but is there a hard-and-fast method for discerning between them?

The composition of the contents is formal logic, the contents within the composition is informal logic. Kind of like a fine art painting, the composition is the placement of the contents within the painting. 

Formal will work with any argument, informal wont. Likewise, a good compositions will work with any subject matter in a painting.

I know of no such rule (not that one doesn't exist). There aren't that many deductive fallacies, so perhaps memorization is the best method.
