Here is Duchess ...

Duchess tested me !
Duchess had some hidden flaws...
Duchess needed some tlc on her paintwork , Duchess certainly made me work , but I still enjoyed working with her, she laughed i cried , I swore , she sighed 🙃
But we got there , and now she looks stunning!
Kirsty Gyllenspetz Dan hope you both enjoyed your holiday xo
