Intricate patterns, whether small or large, must be made of several pieces of wood so joined together by glue that the tendencies of the several pieces to warp may be counteracted. This is accomplished by placing the pieces together so that the grain of adjacent pieces runs in different directions. A very common example of this is seen in the segment work of Fig. 107. Also, it may in some cases be advantageous to note the part of the log from which the wood is cut. The direction in which a board tends to warp is shown by the log end in Fig. 113.
