It's best to hand wash your completed cross-stitch project with mild soap or detergent. Rinse it well so that no soap residue remains. Instead of wringing it, gently squeeze the water out with your hand. Place the damp fabric on a dry towel, roll it up, and press to absorb the water. Adjust the shape of the fabric before laying it flat to air dry. Once the fabric is completely dry, iron it on the reverse side using a low heat setting.
