This "or" That

One of the above blocks was foundation-pieced onto paper, the other patch pieced.Can you tell the difference?

              In the Volume 1 Summer 2013 issue of Quiltmaker Classics (magazine) on page 39 a quilt named "This and That" is featured. Liking the on point centered square for use with some fabric I had on hand, I thought I would give that pieced block a try. The magazine included both a foundation piecing pattern and the dimensions for patch piecing. I up-sized the dimensions so that I could use some fussy-cut Winnie the Pooh fabric for the center square to best effect. Having paper pieced two of the blocks, I decided to try patch piecing one.  Well, above you can see the two blocks side by side. Can you tell a difference?
     The sewing of the foundation pieced block, using paper as the foundation, made obtaining accurate placement much easier, even though it did use more fabric. Also, I can tell that when I begin to join the blocks, by leaving the paper in place for the join, I will know just where to place the 1/4 inch seam. So, yes, I do like paper-piecing, EXCEPT for the fact that I use up more fabric than would otherwise be needed. 

   Oh! Which was which? Below are the same blocks positioned the same way, only flipped. Did you guess correctly?
