We recently ripped the carpet out of one room and just painted the subfloor. Sounds janky, but it looks pretty cool, not to mention easy on the pocket-book. We needed a threshold to visually join the carpeted part with the new, non-carpeted part. I was also being cheap about that and didn’t want to spend money on a long-ass, wood threshold—about 8 feet. After a trip to Ace Hardware where I said, “I’m not paying that”, I went to work on making my own out of some salvaged lumber I bought at an auction.
