Resume?

OK, I need a resume. I have owned and operated D's Stitcheree for 16 years. I know there must be something good I can put in a resume other than I am a SWAHM. I love being a SWAHM but find that I may now have to seek outside employment, at least for a little while. hhhmmmmm how does one compete with much younger workers when she has been at home for 16 years and does not have a formal education. Went to college 26 years ago. Do I go back to school at 56, hubby says no, I would never recoop the cost because employers would rather hire younger workers. I LOVE being a SWAHM and this will probably be mute in another month when my business picks up, BUT, for the time being this is an interesting predicament I find myself in.
