The rosette pattern is transferred to the top using an acid-free, non-directional paper. Paper that is not acid free will become brittle over time and lose its stability – a key factor that is important to hold the fragile wood rosette together. The paper should also not have grain running in a particular direction, since it is glued to the top using a collagen-glue which is diluted with water. When applying the glue to the paper, it immediately swells due to the hydration. If the paper had a specific grain direction, the pattern would become distorted and the rosette would be slightly oval; which is to be avoided.
