Our house used to be all red brick, but it was crumbling, so we removed part of it and replaced it with limestone. It all suits my Gemini nature--the east side is brick and the west side is limestone. Throw in some glass block and stained glass and bright flowers, and it's home! We did most of the work ourselves, so nobody told us we couldn't. I kept the bricks we removed and use them to outline flowerbeds.
I worry more about color combinations on the flowers than I do indoor decorating. Right now, there is a group of bold orange-gold iris next to a massive clump of sweet pink Beverly Sills iris, with a dark red peony on the other side. It feels so wrong it almost makes me sick.
