What does cockling mean?
Cockling is the wrinkling or puckering of a normally flat surface into small, irregular ridges and ripples. It is most commonly applied to paper and fabric: humidity, moisture, heat, or poor mounting can cause sheets to buckle and wave, a defect that conservators, printers, and framers work hard to prevent. By extension, the word can describe a light rippling of water, as in the older literary phrase 'a cockling sea'. The term derives from 'cockle', the ribbed shellfish, whose corrugated shell suggested the appearance of the wrinkles themselves. Cockling carries no strong emotional connotation; it is a precise, descriptive word valued in technical registers where 'wrinkling' would be too general. Anyone who has watched a well-printed page curl and ripple after a spill of rain has observed cockling firsthand, even if they never knew it had a name.

Etymology of cockling
Cockling derives from the verb 'cockle', meaning to wrinkle or pucker, which in turn comes from the noun 'cockle' — the edible marine mollusc with a distinctly ribbed shell. That noun entered Middle English from Old French 'coquille', ultimately from Latin 'conchylium', borrowed from Greek 'konchylion', meaning a shellfish. The wrinkling sense arose from the visual resemblance between puckered material and the ridged cockle shell, and has been in use since at least the early modern period.
