See’s Candies has this amazing online thank-you card maker built into their web site. You can customize the card, add your own photos, and make it look truly personal. It’s $4, but that’s what Amazon charges for generic wrapping paper.
My readers know that lame thank-you notes with a mail-order gift are a big pet peeve of mine.
Make me look like a hero when I send a gift and I’ll be back to send many more.
