I'm going to put a patio into my garden. I've dug out a pit for it and dumped a load of broken bricks which I found elsewhere in the garden into it (there wasn't really anywhere else to put them, so I figured bury them under the patio to act as some sort of sub-base - was that a stupid idea?). I was looking at various other posts and websites referred to on here (particularly http://www.pavingexpert.com which seems to be everyone's favourite), but I'm a bit confused about what to do next. I assumed that I put a layer of sharp sand down until it is flat and at the correct level and then lay the flags on top of that using the "5 blobs" technique? The website seems to suggest you can lay the flags straight onto the sand without having to use mortar at all - is that a viable way to do it? Sorry if this repeats questions which others have asked, I'm a bit confused about all the different answers.
