Where to learn a craft....

I love sayings....poems.....scripture and have always wanted to put them on things and sell them. Where do I begin? Should I take a caligraphy class? I have nice hand writing..... Should I take a one stroke painting class to decorate the signs or whatever I chose to put them on? What are some ideas to put them on? I just keep "thinking" about doing this but I really want to start. I've never taken an art class and I really don't have a clue.

Thanks for any ideas from all you crafty people :)
