What's that sound? Is it the bellowing of Father Christmas on your rooftop? Is it the bells of his reindeer sleigh? Is it the sound of holiday carollers outside your window? Not just yet -- it's the sound of your flower seeds saying "Plant me! Plant me!" This holiday postcard will let your friend or loved one do just that. They just have to plant the seed-paper in soil, and before long, they will be watching their Christmas flowers ho, ho, grow!
