FYI-
we also have threads in 'personal style' and 'accessories' about making your own jewelry, sewing, and customising clothing...
that's where a lot of people share tips for doing your own stuff...it's predominantly personal projects...but some of the people that participate actually do sell their work and take orders as well...

...
for example...
i just dye a bunch of t shirts over the weekend and will post about it in the customisations thread...
