Description: Impressions is an exceptionally soft and smooth thread that is 50% silk and 50% wool. It is extremely strong and a very soothing thread to stitch with. Because of the different properties of wool and silk, even solid colors will give a slight heathered appearance when stitched, adding depth and texture to your needlework without changing threads. This is a wonderful thread for backgrounds and well anywhere you want softness and sheen combined.
