This video by Andrehogbom provides instructions for a gingerbread tree and tree house. Every year they create a Gingerbread house (yes everything you see is gingerbread. No cheating or reinforcements) This year they went for as tiny pieces as possible resulting in this tree made up of some 300 branches, each one as narrow as a match. The tree trunk and the big branches are (of course) hollow and made in two matching halves each. The whole thing is about 50cm high.
