All the things that will make you love the 6in x 24in ruler, including the 60 degree angle marks, apply to our 3in x 18in ruler, except we did not put additional inch-mark numbers in the interior of the ruler.
What a treat using this ruler. Wish I could trade in all my rulers for ones with the simplicity of this one. Most are so complicated they drive me crazy. Bought one like that a short while ago. From now on only this simple style.
