I used my own measurements but yes it is. Was fun to do. I layed out my design according to a picture of another quilt shown on here that someone had made. She didn't have any measurements so I made up my own. I used 4 1/2" squares. The strip was 2 1/2"x4 1/2". The blocks were 2 1/2 x2 1/2". With these sizes, on the blocks have to be sewn a scant 1/4". I found that out the hard way so next time they will be cut a little bigger. The outside brown and blue strip were each 3 inches, then used the same blue for the binding. The corner blocks were 3 x 3 inches.
