Retayne is used to set dye. For example, if you printed a text message on fabric, you can use Retayne to to set it. If you have a piece of fabric you know will fade, you can use Retayne to keep fading to a minimum.
Apply Retayne only once on commercially dyed fabric before washing it for the first time, or before piecing it into your quilt. Choose one of the two easy application methods, washing machine or hand wash. Remember to always test your fabric before washing it.
