Carpet replacement questions

I used a solder gun to cut holes, make fine edges, and deal with the weird synthetic fiber jute. It's annoying to cut with a razor knife, but melts away nicely. It was a lifesaver working around the shifter bezel.

Scuba weights worked great to hold the carpet down overnight to regain it's shape on the floor pan after being rolled up in the box. It was perfect the next morning. I'm sure any other small, heavy weights would work as well. A good heat gun on the backing helps too....I was just too lazy to go that route lol.
