Stay at home moms & working from home

I'm lucky enough to be able to be a stay at home mom for the time being. I absolutely love being able to watch my LO grow. I also have a 9 year old and a 7 year old, and it's great that I can do activities with them, help them with homework, and just overall be here whenever they need me. I would love to make some extra $ though. I want to contribute money wise to my household. So I'm asking all you stay at home moms for ideas on how to do this. I know there are many stay at home moms that work from home. Any suggestions? (Not couponing! Lol)
