I was looking at these,
www.amazon.co.uk/Figo-Flexible-Garden-Frame-Connectors/dp/B0036R8ZXI
which handily come in a pack of six three way and four four ways, ie one house shape. I'm sick of the build quality of bought Wendy houses but making your own requires connectors, so if you've got some of these, how floppy are they and would it build a stiffish structure?
