I cut out many things on my rotary mat with a rotary cutter. It is so much faster than pinning. Now you need to have the fabric and patterns weighted down and over the years I have bought a few pricey pattern weights. I have also used soup cans but they are quite bulky. Last week my hubby and I stopped at a local hardware store and I was browsing their hundreds of little drawers of bolts, screws and washers. I discovered their large washers were quite weighted so I bought 4 different sizes to see how they will work for pattern weights. They work great, hang on my pegboard when not in use and, best of all, were inexpensive.
