@ANIBA, welcome to the Forum.
What a gorgeous wall of beautiful drawings!
Very creative process that also teaches to be thrifty and caring. It was said earlier in this forum that small incremental steps make large steps. Our kids should have a clear understanding how industry works, how the stationaries, tissues, wrapping papers they use every day, come into existence and are being sold. Earlier they realize it, better is the awareness, quicker the diffusion, deeper the peer-understanding and holistic development.
Love it! Good luck!
