This is an interesting study/vacation company that leads textile tours to Uganda. The company is called Venture Uganda. They offer 15 day to 9 day trips and are based in London. The tours are interesting especially if you are interested in the fashion industry, textiles and more.
Little tidbit about Uganda. The Nile River begins in Uganda at a little spot called Jinja.
The prices of the study trips are pretty reasonable. You'll find more background information at Africa Fashion Guide.
