Joining the black board paint craze

I have joined the blackboard paint craze.  It all started with Pinterest, I saw one great idea and then another, and before you know it I'm covering draws and trays and even the paint tin.  Now I'm making more plans.http://pinterest.com/bowersnest/chalk/  
Can there be too much blackboard paint?  People will be cursing it next decade as they try and paint over that wondrous thick black paint.

My sister made up the above joke after opening up our glove box, it sounds positive but is referring to our habit of filling every nook and spare space we have with stuff. During her stay we have taken two car loads to the op shop, gotten rid of 2 wheelie bins and 2 recycle bins of stuff. Made some great finds amongst the rubbish including these lovely prints I'd forgotten about, my sister put them in some old frames - I have a whole box of parrots I picked up at a garage sale a couple of years ago.
