Qld Garden Expo and of all the amazing things to see and plants to look at three things really caught my attention.
1/ Garden Sharp. Lawn and garden tool sharpener. I've already used it on my secateurs http://www.accusharp.com.au/subcategory/1/
2/ easyclip. from http://gre8gadgets.com/ Here's a video link that shows some of its uses. https://youtu.be/j8oDNGfQYXo
3/ And last but not least, PVC connectors for making all kinds of things. I've been looking for a product like this for years but haven't been able to find any until now. http://www.klevercages.com.au/
