Sculpey clay (sometimes misspelled as Sculpy) is one of the oldest brands of polymer clay dating back to late 1960s. The newest of the Sculpey lines is Souffle.
Sculpey Souffle is soft and easy to work, making it great for young crafters or those with hand or joint issues. It has a suede-like finish and takes paint well after baking.
For additional information and a comparison with other Sculpey lines, see Sculpey Soufflé Review from The Blue Bottle Tree.
