PinkStripes, on the right, is a good size & matches with a lot of the other blocks. BUT, it is longer than it is wide. However, it isn't blocked.
Half&Half is simply wider & longer. However, it is also not blocked. But it's a looser weave than the other blocks.
I'll be talking more about this, but this represents a good reason one should (a) block your squares, and (b) crochet a test square to check for tension.
