  We analyze the various morphing structures obtained by actuating Janus
filaments comprising driven and passive sectors and textiles incorporating
driven and passive filaments. Transitions between alternative shapes and
coexistence of absolutely stable and metastable states within a certain range
of relative extension upon actuation are detected both in Janus rings and
textiles. Both single filaments and textiles can be reverse designed to bend
into desired shapes by controlling both the size and orientation of driven
sectors.
