Gotta know: Is there any project that a teenager could make at home and easily directly sell it?
Like is there a project (crafts, woodworking etc) that is easy enough for a teenager and can still easily sell it directly online?
Are there any exact websites that will buy the projects?

Beading is quick and absorbing, stuff like mobile phone charms/bag charms are ideal. You can buy the clasps in hobby shops very cheaply. Thread some beads onto wire and using crimp beads attach to the clasp – lots of colour combinations. Beads can be bought really cheaply new, or scout around charity shops and buy up old necklaces and give them a new lease of life. (These types of items are light and so are easy and cheap to pack and post). There are lots of web-sites with beading ideas/instruction.
