It is advisable to use 100% cotton fabric if the item is to be laundered. Ideally fabrics should be washed and pressed before using. This allows for shrinkage and colourfastness. If the colour bleeds when the fabric is washed, rinse repeatedly until the water runs clear and, if necessary, soak in a solution of 3 parts water to 1 part vinegar. If the dye still runs, discard the fabric. To check that a fabric is colourfast, dampen and lay it on top of a white cotton fabric and press. Check for any dye transferred to the white fabric.
