Laying stone patio flags - Thin flags methods

[fredmila]

I am laying patio stone flags (I believe they are slate), 300x 300mm x 11/25mm thick only. I am putting a sub-base of hardcore as I need to raise the level anyhow. This is in a house rear garden with foot traffic only.
If I cannot just lay them on a bed of sand, but need to lay them on mortar, can I use the sharp sand I already bought? if so, what should be the ratio of sand/cement and the thickness of the bed?

Thanks, useful page. I had not realised that, even when making mortar, sharp sand is better than building sand

sharp sand mortar for paving fred,
when laying bricks soft sand is much easier to use
