High-tail it down to In Watermelon Sugar in Hampden for funky and affordable gifts that are fun to shop for. Recent finds include hand-painted wrapping paper, neon-pink owl-shaped throw pillows, and-our favorite-authentic Turkish linen hamam towels perfect for the beach. The best part: You needn't spend more than $25 to impress Aunt Jennifer. In Watermelon Sugar stocks enough cool stuff to make you embarrassed that you even thought of buying another crustacean-shaped Christmas ornament.
