Find the right words
When "Merry Christmas" won't suffice but you don't know what to write, the Sweet Card Messages app offers plenty of suggestions, such as, "This Christmas, here's wishing your lights come on the first time. Have a light-hearted Christmas." Cheesy, yes, but you're certain to find something appropriate. It also extends beyond the holidays with suggestions for belated thank-you's, new driver's license and even well wishes for those in rehab.
