This is one of the tops I made for one of my son's and his wife for Christmas. I am very happy with it! May have to make one for myself after I get the other two quilts I promised for last Christmas to my other 2 sons and their wives! LOL! This pattern is the Carpenter's Square that I found on the Quilter's Cache website. Here is a link

Time consuming and I found it to be quite a challenge but it was a lot of fun at the same time!
