S.W.
Teachsoap.com and millerssoap.com are good starting places. How old are your kidsi? Do you have any pets that are underfoot with the kids? If they are under 6 do this after they go to bed or are in school. You will be using lye (caustic soda or sodium hydroxide) to make the soap. Post me and I can give you more details.
Soapmaking can become addictive and that you want to make more and more and that means you have to have space to store your soaps. The expense for soaping depends on the oils and fats used exituc are more than your aveage corn, soy, olive, coconut, castor oils tallow and lard. Yes you can make soap that will be much better than the store stuff and you can make it to wash clothes.
Good luck to you.
