Place a soft wire on tube (with a diameter of 1 - 2 cm). Remove the coil and cut along one side - you'll have a lot of rings. Show the child, as by clamping, to connect them to form a chain. Now he can produce and bracelets, and necklaces. Encourage him to join rings not only one but two to one, two connected to the third, etc. very Soon your baby will truly surprise you with jewellery.
