Cut your oak board into 1.5 x 3” pieces to make cutting out the designs easier.
Draw your design onto the boards by using a compass (for circles), a straightedge (for squares), or by tracing a design printed from the internet.
Use your scroll saw to cut out the designs.
Once cut, sand down your pieces for a smooth finish.
Use the sander to scuff front of the cufflink blanks. This will make it easier to glue them onto the wood.
Use wood adhesive to attach the cufflink blanks to the wood pieces.
Once dry, stain and/or poly your pieces.
