I'm mainly a hobby artist, and every single product I've released here is something I needed myself but couldn't find anywhere else to my satisfaction.. :) Most of it consists of dynamic clothes for V4 that I need for my projects.. It's getting better in that department, but was pretty horrible just half a year ago.. 

I totally hear ya on long, wavy and curly hair..

Couldn't find anything.. Worked around it mostly by making custom morphs.. Some of the hairs by bice & outoftouch work for this, along with tons of work with the morph tool :)

The combination of working on a clothing or item for a project, then also releasing it into the marketplace is really fun and rewarding for sure.
