Because of economic downturn in the world, most people have become jack of all trades and master of non. learning skills and not getting a mastery of them because they are testing waters on which of them will eventually pay the bills. I have a friend who during her spare time learnt soap making, baking, sewing yet she's not making money off these skills.
If she is not making money from soap making, baking, and sewing then there's a problem that needs to be looked into, because these three skills you mentioned are not outdated because everyone needs soap to bath or wash, baking cakes for celebration and sewing is fashion so she should be making money from them, how long has she been doing them? How good is she in making these soap? Does she bake very well? And in sewing, does she sew well? Is she consistent in these skills? These are the questions you need to look into to get positive results.
If she's doing all at once and making no money then she should pick from the three skills and focus on it because it's obvious that she isn't good at doing all at the same time. Let her focus on one skill and see how it turns out for her.
