We moved here 12 years ago, did living room, have since done halfway up the stairs (!), sitting room, bedrooms at various stages as kids got older, kitchen had a wall taken out and was redone 7 years ago. I don't really get the thing about redecorating regularly unless its really neessary, though I would love to live in a pristine house, however that's not going to happen with kids and animals.
SO do you redecorate when room is falling apart,or do you have a regular schedule of house improvements?
