What are good, home-based business ideas for a stay at home mum?

I have a few friends who take the initiative to tap on their hobbies be it crafts (making diaper cakes) baking (catering cupcakes for events) sewing (making kids costumes or dolls) or blogging to earn cash This is a super cute idea, making dino tails for toddlers then calling them 'toddlersaurus' heh 😛 https://www.instagram.com/sewistic/
