well....
I suppose the article may be good advice for some, but my entire home has been outfitted from estate sales, with the odd flea market or thrift store item tossed in here and there.
All my appliances, large and small, estate sale items, except for the 2nd hand store stove and the 2nd hand washing machine. Gramma didn't keep that toaster because it was pretty, she kept it because she used it to make her toast! Lol. I have never bought a non working appliance at an estate sale, some of them were a bit ragged out, like a rather Loud mixer I bought, but they all worked.
Linens? Spot on! You can't buy the quality today of those vintage sheets for any price. All my linens are older than me, and in far better shape than a lot of people's that are only a few years old.
Furniture? Again, quality quality quality. The don't build sofas like they used to. I still regret parting with my Austin Powers style curved solid oak sofa done in burnt orange velvet, but it was solid oak, and actually too heavy to move for cleaning and rearranging without at least one extra person, preferably 2.
cookware? You'll pry my vintage enamel ware out of my cold dead hands, chips and all. Chips are fine. Cracking and flaking are not and again, new cookware just isn't made as well.
My house may be unconventional and old fashioned, but it feels like a home and everything in it works and is paid for. If my mixer gives up the ghost I will grieve because it may be several estate sales before I find a replacement, not because I paid 200 dollars for it and it's only a month out of warranty. And chances are if anything does break, it can be repaired, another thing you don't get with modern stuff.
