I think the pens with a brush on one end and finer point on the other are by Fabrico. I do have a suggestion about the 5 inch squares - indicate the sewing margins somehow - with stitching or pencil because when I made a signature quilt for a friend's wedding, it was evident very quickly that even adults have problems staying "between the lines". Also have the squares ironed onto freezer paper to stabilize it to aid in writing on them.
