My friend Cindi, in preparation for an autograph wedding quilt, purchased and tested all the fabric pens marketed as permanent. She took many things into account, such as price, lack of fading after several washings, and ease of writing on fabric. According to her thorough research, the Nano-Liner by Royal Langnickel was the clear winner.
