Common knowledge: viable cardboard boxes for relocations are pretty expensive. Cardboard boxes for banana shipping from the local grocery store are free, but difficult to handle as not foldable. Plus: I do not like those nasty tarantulas crawling around in our home.
Solution of course: Ebay local classifieds. We found good boxes from a family nearby that just moved to a new house. And, surprise: those boxes were already labeled! "Books living room", "kitchen utensils", "Toys Dennis and Sascha", and so on ....
Challenge accepted: packing our own stuff in the used cardboards without relabeling them!
Update late evening: It did not work ...
