I like #1 the best ... for me #2 & #3 are really rigid. #1 has more variation in the design, giving more flow and interest.
I would reverse the very top and bottom squares that make up the 'L' shapes so they are mirror images.
Nice EQ work!
Did you know you can create a graphic from your block or quilt in EQ? File, Export Image - export to jpg, gif, etc. jpg will give you a nice small file size graphic with great colour.
Cheers!
