Moving back to Germany after 26 years... (Freiburg)

Hello all, My name is Katerina and I will be moving back to a small town called Villingen-Schwenningen near Freiburg in the new year. I am trying to figure out how to best ship my belongings over there that is not too expensive. I am not shipping any large furniture, mainly just kitchen stuff, books, a bicycle, a sewing machine and serger and clothing, bedding and towels...furniture I will be buying there. Does anyone have any advise on how to ship it over there ( I am shipping to a friends house).
