The key to success in crafting is to make things people already want, but nobody else is making. Browse through your inner circle or target audience and read comments. A lot of people want to spend money, they just want to buy a product they relate to or something that helps them express who they are.
Just one example of this: plushies. They're not new, they're already everywhere, but niche cartoon character and video game character plushies still sell well because it's a new design being implemented on something people already like. There will always be a new cartoon or game coming out and therefore a way to capitalize on it.
You can also apply this tactic to many kinds of items: clothing, accessories, phone/tablet skins etc.
