I'm a gadget person so I have almost everyone that I've seen! I use my 6.5 X 24" ALOT, I use my 1 X 6 alot, I've switched to Creative Grids, I love them! So much clearer to see thru & don't slip while cutting. I have a 15 X 15 Square, a 12 X 12 square, a 9.5 X 9.5 square,I have a 4 X 4 square, a 2.5 X 2.5 square, a 6 X 6 square, I just bought a 25" 9* wedge ruler, I have a new log cabin ruler which I haven't used, my flying geese ruler & my easy angle. Those are my favorites. I do have some others but the names aren't coming to my hear right now because I don't use them much. I've been quilting since 1992 & have all but wore 2 Omnigrid rulers out! They get scuffed up & cloudy looking so I had to start replacing them. LOVE MY RULERS
