we're closing on our 70's cabin by the lake tomorrow. It has been remodeled more recently than yours but we are going to update and fix gradually. Whoever owned it before us loved blue and EVERYTHING in this cabin is blue. I do not love blue. Some of it is pretty easily fixable, some is not. Every horizontal surface is covered with blue formica. the counter can stay but the kitchen table is getting a coat of paint, the coffee table and end tables will be replaced or modified, etc.
We love that its quirky- its got brass name plates on some of the doors! But some of it- someone put exterior siding (blue of course) on the inside of the bathroom. Eventually, we'll tackle that, but we want to enjoy it so not doing that this week.
The first things to go are the upholstered blue dining room chairs that look ridiculously out of place. A friend donated some that fit better. And I can't live with the blue formica backsplash, so we'll put up black chalkboard contact paper for now, and corrugated tin later. Shopping for replacement items on craigslist as we want to keep the comfy- well loved look it has.
