A self-healing rotary matt is an absolute essential when using a rotary tool. Without a good quality rotary matt, you will damage whatever surface you are working on. My desk and dining room table will tell you the story of oops moments involved with rotary tools. I prefer an Olfa matt. They are self-healing and available in a variety of sizes.
I definitely prefer this cutting style to old fashion scissors. A rotary tool allows you to quickly measure and cut your fabric. It also helps to ensure that your squares are consistently sized and your edges are clean.
Rotary Cutting Rulers
I use my acrylic ruler for a variety of crafts, to the point that I had to purchase a new one because I rubbed all the numbers off of the ruler. I have a variety of different sizes in my collection now. My two favorite ones are my 12”x12” and my 6”x24” sizes. I use these the most frequently.
