I use the pens I bought at a quilt shop (pigma) to write on the back of my quilts. My granddaughter is 4 now and i made her a quilt for her first birthday wrote a message on the label attached it to the back of the quilt and it still looks as good as when I did it. She drags that blankie everywhere, my daughter has to wash it almost every other day. I think she 'll wear the quilt out long before the writing wears off LOL :lol: :lol: :lol:
