This pattern is available from Payhip via the pattern website linked above, or from LoveCrafts here - priced in Euros.

The Badbury shawl is offered in two gauges, one for 4 ply yarns and the other for sport weight. Following an ‘interesting’ game of yarn chicken on the first sport weight prototype, the pattern was re-knitted in 4 ply and worked fine with the extra yardage and smaller needles. However, I loved my Corriedale sport weight version which I was wearing daily by then so much, that I reworked the pattern so nobody else had to play chicken like I had. The result - 2 different but very similar patterns supplied as two separate pdfs.

The combination of the garter stitch and contrasts sections work up in such a way that the shawl is reversible and some people prefer the reverse side to the right side.
