Quilter's Rule 6.5X24" is the best. Those grids on the reverse side really grip the fabric. I am still using the one I bought about 25 years ago. I have many other brands but nothing compares to my Quilter's Rule. The only other ruler I use is a 6.5"X6.5" for cutting small pieces. My other brands stay underneath my dresser in my bedroom. They never see the light of day.
