Now I know! I have always used the method of inches plus or minus 3 more lines etc. Hugs and flowers to all, Suzanna

Be sure to count how many slashes there are between each inch line. I have a ruler that is divided by 20ths--not 16ths! Sometimes that method of inches plus or minus lines IS appropriate.

This is a good demonstration what all those lines are for. Thank you for sharing

Amazing how much is stuffed into a simple measuring tape, isn't it. I figure when I stop learning, I will be dead. So keep on teaching us new thing things.

At 71 years old, I still get confused. Thanks for the illustrations...
