sorry I have no one in a size large to try it on to see how it would work on them but should work just fine if you change the pattern to have 2 chains between v stitches in rows 13 - 31hook is actually a steel size 2 which is 2.2 mm
an aluminum size B was the closest
8 buttons I used mother of pearl
