Congratulations on your new home!
I find moving & decorating a new place to be pretty exciting, which is kind of ironic because my family & friends tell me that each of my new homes look just like my last. I guess I like what I like & tend to stick to the same things. As a few other posters mentioned, I too love yellow walls and white trim, so I've had it in every house. I know that the shades are slightly different from house to house, but others don't seem to pick up on these nuances
My kids tell me that I decorate my homes like Christmas trees....red, green & gold. I have loved the Old Country Roses china pattern by Royal Doulton since I was a child...and I still love it, so those are the colours I tend to go with in almost every room.
Is there anything that you love every time you see it? Something you always find appealing? If so, I'd start with those colours.
