Hmm,
I'm no help Shiny - though have enjoyed reading this thoughtful thread.
I have almost no opinions on decor beyond liking what a new coat of paint can do.
Our furniture is mostly Ikea, our house more cluttered than many because our church doesn't have a building, but I hope it is welcoming for the students we mostly have there, who don't seem put off by a couch that sheds bits.
My fantasies in the house realm are all functional - I design kitchens in my mind, and scenarios where the wardrobe is situated such that I don't have to get my clothes out in the morning while is is dark because DH is still asleep.
All that said, when I go to other's houses who have an aesthetic vision I do appreciate it!
