Making letters more interesting - from Vickki

Hello. I am very interested in some of your ideas to make letters more interesting. I enjoy writing to my partner and try to make my letters funny so they cheer him up.
I know what people mean when they say they can get stuck for words so anything that can make letters more interesting is a bonus. I am definitely interested! My partner has been in prison for 7 months and is released next year. Even though I speak to him on the phone every day, he says he always looks forward to getting my letters and that he tends to read them over and over again. 
Please let me know when something is available for us! From Vickki
