Learn to get perfectly centered quilt blocks without doing the math

[rascalfinchbird]

I purchased this ruler and I found it to be a really very, very thin material.I was expecting at least the thickness of a regular ruler.It will break easily due to the thinness of it.For the price,it was very cheaply made. Not satisfied at all with how thin it is for the high price of it.

It's really hard to see the lines on the Block marker tool with the dark blue background. It shows well on the quilted blocks though.
