I have mine flat on my cutting table in my sewing room. It is always there because I use it almost every day. I love it. Best way to find out if you can make holes in it is to contact the seller himself. He was very helpful when I had a question. Email the seller
thru Amazon. Best cutting mat I ever own, and I own several over the years, totally odorless. Good luck.
I keep mine under the couch. It's not visible and easy to get to. Under the bed or on the back wall of a closet would be fine too. If you have a work table in the garage or a designated work room, I would just use it as the top layer of the main crafting table area.
