I have also made several Block B...
But, I have been thinking about changing the center of B block to a purple ... giving the block a slightly different look (green is not my favorite color and had I realized how predominent the green would be I would have swapped the blue and green colors. But since it was a mystery... it is what it is and I can live with it.
|Alternate Block B|
And here the all the blocks are laid out ... but i can't decide if I like the purple or green center on the B block better.
|Assembled Corner Alternate Block B|
Any thoughts or suggestions?
