After almost a year, I finally got up the courage to finish this:
The pattern is my own (though I certainly can't take credit for a simple 9-patch/Irish Chain); the fabrics are various calicos and 200-count muslin. The backing is a white-on-white print. The colored squares are quilted in a variegated cotton thread from Valdani, and the white squares are quilted in white cotton thread (all by machine). It still needs a label, which I will get to this weekend sometime.
Daughter thinks this is for her, and I don't know, maybe it should be. I suppose there's no point in just hanging it on the wall, or worse, folding it away in a trunk or closet.
Excuse me, I need a kleenex.
