Decorating tends to be on a "needs must" basis here - I'm not one for constantly changing things, I can't stand all the upheaval. As for changing furniture regularly, doing a total makeover, no, not for me. I like what we have, it's in good condition, so really don't have a desire to change it just for changings sake. Not sure how people afford to do it on a regular basis, anyway.
Admittedly, the decorating looks good once it is done, but I can't understand those who decorate twice yearly or even every year (unless you live in a very smoky environment, perhaps). All I can think is that they love doing it, which I don't. Having said that our bedroom and the bathroom are in need of freshening up, so that is this summers project.
