Cover work area with paper towel. Lay your shirt on a flat covered surface. Pinch up a part of the shirt (both layers) and twist. Repeat this process all over the shirt. Using Simply Spray, shake can well, pull off blue safety tab, spray the entire shirt. (For darker coverage, spray over twice.) Wait about 10 minutes for the shirt to begin to dry. Open the shirt. For a 2 colour twist, repeat the above process with your second colour. It is not necessary to let the first colour dry before applying the second colour. Shirt will be dry to the touch in about an hour. Allow to dry thoroughly (72 hours) before washing.
