Solid Wood Toggle Buttons. These are great for jackets and coats, especially on children's wear. To attach them to your knitted project, loop a braided cord or crocheted chain through the toggle and back into your button band. Then make a second loop and use that as your 'button hole'.
The natural wood and smaller dark wood toggles are 3cm long and 0.7cm wide.
