Also keep in mind that the effect of the block varies greatly not just with the layout, but with the relation of the curved piece to the background.
These are all the same size blocks - but the the visual is very different depending on the make up of the block.
The left twist is a favorite of mine for borders.
I really like the smoothness of the edges.
Again, the block size is irrelevant.
Most patterns that I see, though, use blocks that are similar to the one in the middle twist

You can see it here in a simple barn raising setting.
Again, blocks are all the same size.
Since the DR block has the same color distribution of a HST block, you can create any Log Cabin setting with the DR blocks.
