JJ, I think that's what would be great about it. There are embroidery pens by which someone could create a square. There are iron-on photo options. There is quilting, itself, to create a square to add into a quilt. There is embroidery stitching. There is smocking. There is tatting. Let's see, what else? Even if someone used fabric paints and put a hand print (or something) on a square. Or, ironed on lipstick after kissing the fabric. Poets could write a poem, writers a quote or very short story. Lawyers could pen out something about women's rights. Beaders could bead.
Imagine.
