It is amazing how many looks we can get from this man made fiber. It can fool us into thinking it is silk, linen, cotton or wool. It is more reasonably priced than the natural fibers BUT it doesn't hang in nice folds for drapery and has a tendency to flare out at the bottom. We can correct this problem by adding memory stitching at the hemline which is an additional service. Consider the additional cost for this service when specifying Polyester fabrics for draperies.
