Actually, a terrible pun! Penny came up with this title. Actually she comes up with many of my titles and I have said that when she is at uni I am going to have to Skype her and show her my layouts so that she can come up with the titles!
A chine is 'a steep-sided river valley where the river flows to
the sea through, typically, soft eroding coastal cliffs of sandstone or
clays' (Wikipedia) and we visited the one in Old Shanklin whilst on the Isle of Wight.
I used the layout from Shimelle's 'And now for something completely different' for August. You can see the suggested 'kit' here and the steps here.
And here is my layout.
