Interesting is how interesting you make and who are your readers.
Stick to basic rules of good writing. A para consists of one or more sentences. A para should express one single idea. There could be three ways of doing it depending g on the place of the para in your narrative. Once again their is one idea or conclusion. T0 support this idea, conclusion there are other supporting ideas.
You could begin with the idea and subsequent sentences support, confirm, amplify or even give examples or draw from other writer's. You could place it in the middle of the para. This is a tough way to express and experienced writers follow it. The last is to Marshall your thoughts ideas etc and end the para with your concluding thought, idea, conclusion.
Good rule. Do not overstretch and have one idea in each para.
