Answer:
Curly Birch refers to a type of wood grain pattern found in birch furniture. It is characterized by a distinctive swirling or wavy pattern that resembles the curls in curly hair. This grain pattern is caused by irregularities in the growth of the wood fibers, resulting in a unique and visually interesting appearance. Curly Birch is highly sought after in furniture making and is often used to create decorative and luxurious pieces. Variants in grain markings in some woods show strong parallel waves or curls.
