Do you quilters out there sign your quilts? If so, how do you do it? Do you embroider labels? Do you do it with a permanent marker? I am debating whether or not to label the block swap quilt that I am planning to give away. I am too lazy to embroider a label for it (mostly because I am itching to get it done) but I am afraid that a permanent marker will fade and look bad over time. Are there special markers that you are supposed to use for this?
