There is also a Christmas teapot that goes on the trivet on the cart, but I will save that for another day.
I have two Christmas tea houses, the Canton tea house (I love the Asian inspired portico complete with handing lanterns on the English cottage!):
and the English tea room:
The patroness of the English tea room also has a portable cart so she can take tea out about the town. If you look really closely, written on the side of the cart says "You are cordially invited to attend a Tea in the Afternoon in the custom of Anna, 7th Duchess of Bedford." Such great little touches!
