Do you know how long it takes to sew decorative/reinforced stitching around the perimeter of a king-sized down comforter?
It takes a loooooong time. But man, that comforter has been with us for a long time, too, and man, it had lots of holes around the seams.
And hauling it triumphantly back to the bedroom when I was finished, finding Matt laid out on the bed playing video games, and flopping the comforter on top of him, watching him first flinch back and hold his breath in anticipation of the expected cloud of downy little feathers, then smile happily and say, "Hey, you fixed the comforter!"--totally worth the trouble.
