Method of making wooden board assembly

A method of making a wooden board assembly comprising steps of:

• A) determining a scrap portion on a center of a tree trunk, wherein the scrap portion is rectangular or circular, the trunk includes two wide board areas located on an upper end and a lower end of the scrap portion, and the trunk includes two narrow board areas located on a left side and a right side of the scrap portion;
• B) cutting the trunk horizontally in a predetermined thickness to form multiple boards, wherein the multiple boards include multiple wide boards, a narrow scrap board at a top of the trunk and a narrow scrap board at a bottom of the trunk;
• C) removing the narrow scrap boards and two trimmed sections of each of the multiple boards to obtain multiple trimmed wide boards, and cutting each of the narrow board areas from the scrap portion to form multiple peripheral boards;
• D) removing a part of the scrap portion and two trimmed sections from each peripheral board of the multiple peripheral boards;
• E) connecting each of the multiple trimmed wide boards with multiple peripheral boards to form a substrate, wherein each of the multiple trimmed wide boards and each of the multiple peripheral boards is cut in a same length;
• F) adhering two straps on two ends of the substrate to produce a wood pattern assembly;
• G) cutting the wood pattern assembly to form multiple cut films;
• H) adhering each of the multiple cut films with a nonwoven fabric by using a transparent adhesive and connecting the multiple cut films on a fixing lamination;
• and
• I) cutting the fixing lamination in a predetermined length and a predetermined width.
