crazy ideas

My mom and I went to a craft boutique a couple of weeks ago.  I wanted to see what was the popular thing going.  It seemed to be the "pillowcase dress".  I inquired into their fall show and was told that I could sign up.  I was trying to figure out what kind of things I could make.  One thing I would like to do is fabric covered buttons (with embroidry letters)  both pins and loop backs.   Im not sure what else I would want to put into a collection that would be different and still make money......
