, for details on experimental methods, typical contact angle distributions, a brief discussion on governing parameters, two figures comparing experimental and numerical formation dynamics for rectangular and square lattices and three movies. Movie S1 illustrates experimental Haines jumps and the resulting formation of walls

, The surface tensions determined by pendant drop tensiometry are 35 mNm ?1 and 36 mNm ?1 for the SDSbased system and Tween 20-based one

, We consider a typical length scale of wettability heterogeneities given by that of a meniscus and a rectangular distribution of contact angles ? for the sake of simplicity
