WikiHow might be a helpful source for many existing and new interests. How to make your own clothes for instance is covered there along with very many other topics. REMEMBER however that these articles are put there by people and are not guaranteed to be correct. So don’t do anything if it looks dangerous and maybe ask for help as well as using the information provided. Also, the site contains a lot of adverts so be careful where you click. After saying all that however, it is a valuable source of information. Caution is always recommended when using internet sources, even this one. There is no substitute for good thinking, so think as well as research.
