Some of the most trusted medical authorities, such as the U.S. Centers for Disease Control or the World Health Organization, have consistently suggested wearing masks to prevent the spread of Covid-19. Of course the safety of masks is limited, because the virus can be transmitted in other forms (such as touching), but it is much better than not using it at all.
In terms of home-made masks, of course, the degree of protection is not the same as surgical masks, but even in this case, experts say that they are better than not putting at all.
Homemade masks, which save you money and can be washed, are advised to be made with complete materials, such as cotton, for example. Here are some illustrative videos on how to sew or create them without having to use additional tools.
