DESCRIPTION:The procedure of curling a ribbon by running it over a sharp b
 lade is commonly used in wrapping presents. We examine this phenomenon usi
 ng experiment and theory\, investigating the dependence of ribbon curvatur
 e on blade curvature\, the longitudinal load imposed on the ribbon and the
  speed of pulling. A surprising experimental finding was the non-monotonic
  relationship between the applied load\, which forces the ribbon to curl a
 round the blade\, and the resulting radius of coiling. We develop a model 
 which identifies this non-monotonicity as a self-limiting effect of the re
 laxation of the ribbon.
