I finally finished this on the 12th of March 2016. Here’s what it looks like!
Stencilling should be done with sponges and not regular paintbrushes. I had to learn this by experience.
Not only can it take the weight of a toddler, it can take the weight of two toddlers and one me, making it strong enough to support 80kg+!!
And the kids loved it, so it was a job well done. The end.
