See these? These are the little area rugs we bought from Ikea a couple years ago. We've got five of them in the kitchen. A couple of weeks ago, Serge threw them in the washing machine. (When we got them, this was a main selling point. Sure they are small enough to fit into a washing machine, but just to verify on the tag, yes, Machine Washable. )
So Serge washed them and then placed them back in their spot to dry overnight. Some days later, as I was vacuuming, I went to move the rugs so I could vacuum underneath, and they wouldn't budge. It seemed like they had been glued to the floor. As I tried to lift the rugs, it was like pulling on really sticky tape. And then this:
It seems as though the wet carpet and the varnish had some kind of "superglue" reaction and now if we pull up the carpet, the varnish and stain on the floor come up too. I was and am horrified at this. The tag certainly didn't alert us to any danger to our floor from the carpet. (Which would be very very salient, considering you would be placing the carpets onto the floor.) When Serge saw it, he was delighted. Why? Because now we can REDO the hardwood floors. Of course he's right, but my solution is going to work just as well at a fraction of the price (and work). Buy new area rugs for those spots! This could become a source of future discord, I'm sure.
