Handi Grip
I have never been able to hold my rulers straight when cutting fabric. I do have small hands. I tried The Gypsy Gripper, the large suction handle and it helped but still moved near the end of the cuts. I ordered these Handi Grip and boy do they work. All they are are strips of emery board type material with an adhesive side. You can cut to the size you want and place on rulers or templates. They are clear so even when you put them on the back of the ruler you can still see the markings. Supposedly you can remove and reuse but I haven't done that yet. All I can say is for me it works great!
