I have a special love for printables (stationery that you can print on your own printer) - they are economical, you can print on any kind of card stock (go eco!), any time and you can use them again and again. Mooo have some cute designs on their printable greeting cards that you can personalise with your childrens' names.
Head over to the Mooo website, personalise, then download the image. You can print it, or save it to your computer and print later. Enjoy!
