Since then, things have moved on: I've turned another pillowcase case into a rather lovely cherrystone cushion. You fill the bag with the cherry stones, sew the flap down sturdily, and voilà.
If you haven't met a cherrystone cushion, they serve the same purpose as hot water bottles, but more elegantly. Three minutes in a microwave or fifteen minutes in an oven leaves the cushion beautifully cosy for a few hours. It's washable, throwable, looks well on the lower shelf of one's obligatory French-style bedside table, and doesn't drench inquisitive children.
Three lifestyle points to me. Trí phointe, trois points.
