Examples of Bronze Age wood-carving include tree trunks worked into coffins from northern Germany and Denmark and wooden folding-chairs. The site of Fellbach-Schmieden in Germany has provided fine examples of wooden animal statues from the Iron Age. Wooden idols from the La Tène period are known from a sanctuary at the source of the Seine in France.
You can transfer a graphic on any wood piece of your choice, including a frame, top of a table, etc. The surface should be clean and big enough for the graphic paper. I am also sharing a video tutorial here that explains in detail the process of transferring any graphic to a wooden surface using a freezer paper. Just gather the items you need and follow this video to carve your favorite designs on your favorite wood items.
