Some of you asked where to find a similar tea set like the one Hetty's using... today one fellow fan answered your Q...
It's Royal Albert Old Country Roses. Any major department store like Macy's or Dillard's has it. Also check out Ebay.com and Replacements.com, among others. There are many, many variations on this classic pattern, so be careful and compare the pictures if you want the same thing as Hetty. FWIW, as bone china goes the prices are quite reasonable.
