I made the Links quilt last year. It was a dozzy. Re-read the instructions. I don't remember it now, all my sewing is downstairs. but I'm thinking that the square's are 11" and 9". I had a hard time with it also. I don't think I could have put it together without my design wall. Try putting them in the layout design and see if they fit together and look the way it is suppose to. If all fits into place and all the other parts fit, the size of the blocks will work out.
