Looking for a fun and unique woodworking project? Consider making a DIY wooden rainbow stacker toy! This toy is not only beautiful to look at, but it also promotes hand-eye coordination, fine motor skills, and problem-solving abilities in young children. To make this toy, you will need a selection of hardwoods in different colors, a saw, sandpaper, and some woodworking glue. Begin by cutting the hardwoods into strips of equal width and length. Then, sand the edges of each strip until they are smooth to the touch. Next, arrange the strips in a rainbow pattern and glue them together. Once the glue has dried, use a saw to cut the rainbow into different-sized arches. Finally, sand the edges of each arch until they are smooth. The result is a beautiful and functional toy that will provide hours of entertainment for young children. As they stack and unstack the rainbow arches, they will develop important skills that will serve them well throughout their lives. So why not give this project a try? It's a great way to exercise your woodworking skills while creating a timeless toy that children will love.
