The objective of this study was to increase the utilizability of domestic thinning and small diameter wood as applying in pattern design which can be applied in interior decoration, wood craft and wood furniture, and in developing the designs of furniture and household items. Then we investigated the physical and mechanical characteristics of Acer mono wood by pressurization and heat treatment. Color change is clear, and the wood density is increased with increasing pressing rate. The compressive and bending strengths are decreased as heating time is increased after pressing. However, shrinkage is improved after pressing and heating.
