Branches are an important material, but often times take up too much space. Once you start making bricks and begin to bake these things are needed in mass. Yes, there is the option cut logs into blocks but I rather use logs for building material rather than fuel. So I propose we be able to bundle sticks to save inventory and storage space. Bundles would work similar to a seed bag, holding up to 9 branches. Possibly other materials could be stored in a similar manner, like straw and plant fibers.
Extra mechanics, not necessary to the main idea: To start you would need at least 2 branches and string to craft a bundle. When you create the bundle it will initially contain however many branches used in its construction (2-9). To dismantle the bundle, remove all but 1 branch from its inventory (you can't have a bundle with only 1 branch, can you? Other wise its just a branch with a string attached). When the bundle is unraveled you regain the string used and the last branch in its inventory.
