18. Sell Crafts
Crafts items are things that almost anyone can sell for cash – including kids.
Crafts can include things like bracelets and keychains, but older children could create more elaborate items, such as jewellery.
Costume jewellery sells extremely well online or through places like Etsy – and the great thing about creating it is that you can also go to places like flea markets and art shows to sell your items.
