I now have laminated height chart posters available in my shop www.MySweetPrints.com.au
The height charts measure 30 x 90cm and are matt laminated to be sturdy and waterproof.
They cost $49 + p&h and come delivered in a mail tube.
You can also buy the canvas version in my store under 'canvas art' which is slightly longer.
What do you think? I'd love to get your feedback!
