While Skinny Bone Jones gets crafty with a too-big ring and a scarf, I get crafty with a strip of stretchy black fabric and a $2 brooch from the thrift store.
1) wrap fabric around head like headband, tie.
2) wrap small strip of fabric crosswise around the knot.
3) pin brooch to this spot.
4) pretend this wasn't a last-ditch attempt to dress up an otherwise nondescript ensemble.
