In the following two decades she produced more than 70 highly original textile designs for Heal Fabrics, as well as responding to commissions from numerous other companies in Britain and abroad. The V&A's Lucienne Day collection includes dress fabrics, furnishing fabrics, tea towels, wallpapers and carpets, as well as examples of the one-off 'silk mosaics' she designed during her second phase of creativity from the late 1970s onwards.
