I host and run the table runner swaps here on the board. I personally think something in Christmas fabric should be delivered well before Christmas as a gift. If its a Christmas gift why not use winter fabric? the beautiful blues/whites/silver snow fabrics? absolutely make the back a reversible could use in another time frame.. just bind it in coordinating colors to match both sides. Say if you use blue/white then do the back in hearts and roses for valentines day you could bind it in white so it is easily flipped. Those are the runners that make everyone happiest I think a dual usage item.. keep in mind the persons home colors when making them and they will get lots of love for a very long time. (ie if they have rust and green don't make a blue and pink runner)..
