Well, if you know what they like to eat: canned nuts, fruit, candies -perhaps a basket of these items? Obtain a simple basket and wrap the items with an attractive bow or nice scarf if a bow is unavailable. A good friend faced this problem one year, and brought our kids a huge basket of Little Debbie cakes and snacks. The kids loved 'em. If you aren't interested in food items, a bundle of colorful candles perhaps, maybe throw in some incense. If your friends like wine, you could try a bottle with a simple bow wrapped around the neck. A plant for flower lovers is an idea, too. And money cards are pretty easy to come by these days. Good luck and Happy Holidays!
