I was pretty excited to see these cards at Target a few weeks ago. They are similar to some that they used to sell but discontinued. They work so nicely with the custom stamp from Impress. The stamp is called Hello from (your city), in my case I used my state since my city name is a bit too long.
These are the discontinued cards that Target used to sell. They were rectangle and the newer ones are A2 size. I love those little houses and was so happy to see them on the shelf again! It's the little things :)
