Forget the vacuum with pantyhose stuck on the end. Forget crawling around on your hands and knees. This is guaranteed to find every piece that was tweezerpulted into the gaping maw of the carpet monster.
The carpet monster is apparently a sentient being that survives in multiple plains whereby it not only biologically bonds with each individual fiber of the carpets, the putrid gas it gives off fills the air space between the fibers. This essentially makes the entire carpet the monster. I know now that “carpet monster” no longer refers to the monster that lives in the carpet; more is that the carpet is the monster itself. However it is infinitely more fun to view it as the former than the latter.
Step 1. Go out and buy $1500 worth of carpet to redo the room where your bench is located. Think about it… what other reason in the world would you undertake steps 2 & 3. (Yes it was SWMBO that mandated the action)
Step 2. Move every stick of furniture out of the room. Have fun trying to figure where to put a room full of furniture into rooms that are full of furniture.
Step 3. This is where the fun starts. Cut the old carpet into manageable pieces to be removed. As the “carpet” is disemboweled, the lost pieces will fall to the floor and all you have to do is sweep it into a pile, put on a dust mask and pick through the crud.
You would not believe the pile of crap I found from so far back I barely remember losing the stuff.
