One day I was working on a craft project in my living room that involved a drill. As careful as I was, I drilled into my carpet and ended up winding up a 3 inch x 3 inch square of carpet around the drill bit - essentially gouging a huge hole in my carpet.
After some extensive searching, I found a very unique, but very cool service called "John's Carpet Repair".
This guy (John) came out and transplanted a square of carpet from the closet to the square in the middle of the living room.
A very skilled operation, John carefully but quickly and skillfully mended in a new piece of carpet. Within a week, the color difference was indetectable and the "gotcha" was gone.
I couldn't find anyone else who could do this - so if you ever screw your carpet up, you gotta call John.
This repair took him about 30 minutes and about $70 - well worth it. Amazing!
