Quince Cotton Slub Curtain White 48x96 Light Filtering. Selling an extra that I didn’t need. One panel. More of a warm white than a bright white. Give your windows the treatment they deserve with our Cotton Slub Curtains. Crafted from 100% cotton, these soft yet durable curtains feature a unique cross-weave pattern with a natural, nubby texture. The slub effect creates beautiful variations in the fabric, giving the curtains an approachable, organic look. Hang the curtain from the back tabs for an elegant pleated style, use the rod pocket to create a more relaxed, gathered look, or hang with a set of our curtain clips.
