I forgot to say that your basic rulers may be something you need to see in person before you buy. My 6" X 24" Omnigrid is probably 20 years old. I have used it for sewing and quilting and used to love the markings to the 1/16ths. But now I have trouble seeing that arms length distance as clearly as I used to, even with new glasses. Those tiny yellow/black markings aren't so easy to see anymore. I found the June Tailor Shape Cutter Plus on sale at Amazon, and found that in addition to the slots, I liked the black ink. I may have to save up and use a coupon to buy a new utility 6" X 24" ruler with black printing.
