Help with planning a curved path - How do i plan a curved path

[Snowychris]

I am trying to plan a curved path in my garden. Part of it will be straight (I can manage that) but then there is a 10-foot long stretch of path that has to have a concave and then a convex curve. These curves move the path two-feet out from the starting point then it is straight again along that different line (I hope this makes sense, I have never done a path before). The straight part of the path will be done in sandstone in random sizes (left over from laying a patio) - the minimum size is 300mm x 300mm. There are some matching slabs available at the builders' merchants in 150 x 150mm. I was hoping I could use these, for a contrast and to avoid me having to cut slabs - I have no cutter and do not feel comfortable to start learning how to cut slabs now, as I am not confident with machinery. Can I lay 150mm slabs out so that the joints are not too wide? How can I work out what the curve will be (2' 'shift' over 10' length)? I would be so grateful for any advice. Thank you. (I am a novice at this, but at 70 I believe that you are never too old to learn!) Snowychris

Don't think this path would be possible without cutting. There's more experienced people on here that should be along

Thank you for your advice.
Perhaps I will have to move the shrubs and have a straight path.

Lay out a length of rope or garden hose to form the curve.
You should get away with using the 150mm setts but make sure the pattern runs linear with the curve rather than trying to maintain a straight row of setts across the path.
