Making paving slabs

[Terrian]

I bought this plastic paver mould thing years ago for about $20.
Its about 600 mm across.
Place it on the (prepared base) ground, fill it with concrete, tap, remove and rotate it as you go to so it all fits together.
I trowel some black and red oxide over the top for a better finish also.
Its pretty quick and the finished result looks good.
Dunno if thy're still available though.

Can't recall if it was Melcan or Blue Circle that had those, but you bought them and bags of pre coloured concrete to make your own crazy paving walways, we sold hundreds of them )
