New sandstone patio - edging question - Edging first, or last?

[diy_jim]

Hi, laying a new sandstone patio in the back garden, around 30m2. Id like a tegula edging all the way around, should i install this first, and cut the slabs to finish, or do i lay the slabs first, then finish with the block edging?

Thanks

edging first mate is a proper job maybe do 2-3 sides to give yourself a bit of wriggle room if it doesnt pan out exactly as expected
