If you're trying to describe a piece of wood that has an even and consistent pattern, "straight-grained" may not always be the best term to use. Fortunately, there are synonyms that can be used instead. For example, "even-grained" can convey a similar meaning, as can "regular-grained" and "consistent-grained." Another option might be to use a more specific description, such as "fine-grained," "coarse-grained," or "interlocked-grained," depending on the nature of the wood in question. By choosing the right synonym, you can ensure that your description accurately conveys the qualities of the wood you're discussing.
