1. A method comprising the following steps:
- a) applying a laminate to a substrate to form a bond between the laminate and the substrate;
b) pulling on the laminate in the direction of the plane of the bond to separate the laminate from the substrate;
c) reapplying the laminate to the same or another substrate to form a second bond between the laminate and said same or another substrate; and
d) pulling on the laminate in the direction of the plane of the second bond to separate the laminate from said same or another substrate;
whereinseparation of the laminate from each substrate is effected without leaving any residue of the laminate on the substrate; and
the laminate comprises;
i) an elastic support with a resilience of at least 80%; and
