With the Ravensburger BeCreative String Art Set Butterflies, children aged 6 and up can learn the popular technique of String Art. Instead of using nails, plastic pins are pressed in. Once all the pins are in place, colorful threads can be stretched across the front of the board in any desired pattern until the thread weave reveals the design. Each person decides when their thread picture is finished. String Art is back in trend. With the Ravensburger String Art Set, elementary school children can easily learn this popular technique. It's very simple: the holes in the motif boards are color-coded on the back, making it easy to see where each pin should go. Once all the pins are inserted, the matching colored threads can be stretched across the front of the board in any desired pattern until the thread weave reveals the design. Each person decides when their picture is complete. The weave can be very dense or have many gaps. The set includes plastic pins in various colors, two motif boards with templates, and threads on spools in different colors.
