I use one/sometimes two, 5 pound exercise weights - one toward each end of the ruler. I started doing this after seeing Donna Jordan of Jordan Fabrics use a weight. It stopped my ruler and fabric from moving, which it can do even with the no slide backed rulers, or tack dots or strips on the back of the rulers.
A lot of acrylic rulers are not completely flat and are definitely not heavy enough to hold down and keep the fabric from moving. You need weight, either your hands or like I do, using both my hand as I go along and an exercise weight or two to keep the ruler in place and in total contact with the fabric. I also still take the time, when I am making cuts, to hold down the ruler opposite of where the blade is cutting, as it is cutting, to make sure the ruler is actually in contact with the fabric and holding it secure.
