I've made a tie quilt, I hand washed all the ties in woolite to remove sweat and cologne. I line dryed them, the silk ones held up very well, only the older rayon type ones from my grandfather had deteriorated to the point that the fabric was unstable. Interfacing is a must due to raveling and the bias of the ties. Mine was a mixture of all types of materials. Since the 70's and 80's polyester was big.
