Hello @MaryLeeM89 ,
Are you wanting to physically send little postcards made in CTCT? In that case, I'd recommend making your full postcard and then using the Print / Download method to get a PDF, PNG, or JPG version of it. Then you can print them from your device, write in your contacts' individual names, and physically mail them.
If this isn't what you're wanting, can you elaborate a little bit on what you mean by labels? Is there something in our system you've used previously for your Christmas cards?
