You all would be right IF...
I had not forgotten about the center square! Uggh!
I think when I typed the message yesterday, it had just been too long of a day!
For some reason, I was coming up with 48" instead of 54" for a yard and a half.
Well, since I have now remembered the center square, I will need to go shopping anyway.
Don't you hate days when your brain stops working? Thanks for your help everyone. I knew I could depend on you, too bad I couldn't depend on me! LOL
