Get them!
I purchased the Peek-A-Boo Christmas Train set. In order to "stretch" my supplies, I also ordered this set. I can use it with the train to make more cards for birthday, valentine, thank you and many other occasions. You can also make 4 1/4" x 5 1/2" or slimline cards when you pair this with the train. It's well worth the extra expense! Of course, you can also use this set on its own to make lots of cute cards!
