Butcher`s paper is a good idea. Just leave a little extra for fine tuning during the install. Otherwise, you run the risk of a nagging corner that was trimmed a little too close. Murphy`s law will ensure its in a most visible spot as well.

I used spray adhesive from JC Whitney which came with their insulated matting (aluminum/fibre/aluminum sandwich). It appears to be spray rubber cement, also sold by 3M.

If you spray one surface only, and let it cure for 10 minutes or more, the carpet will be more readily removable in the future. Doing both sides, as I did on my dash, makes is a more permanent installation.

Good luck!
