It is of interest to fabricate curved surfaces in threedimensions from easily available homogeneous materialin the form of  flat sheets. This talk will report on threegeneric methods developed by us  for molding a flatsheet of thermo-responsive plastic by selectivecontraction  induced by targeted heating. Thesemethods do not involve any cutting and gluing which is aproperty they share with origami. The first method isinspired by tailoring which is the usual method formaking garments out of plain pieces of cloth. Thesecond method   aims to bring about the desired newRiemannian   metric via an appropriate pattern of localcontractions. The third method is based ontriangulation, and seeks to induce the desired localdistances. The second and the third methods, and alsothe first method for the special case of surfaces ofrevolution,   are algorithmic in   nature.  Along with anaccount of these methods, I will show photographs  ofdifferent shapes that we physically molded by thesemethods. This is joint work with Shankar Ghosh andHarsh Jain of TIFR, Mumbai.
