Yes the 4 patches all need to be blue and cream in all the blocks and in each block the blue and cream needs to be the same but the blue and cream can be different from another blue and creme in a different block. so we have some sort of unity I hope that makes since. So block "A" blue and cream are all the same, but in Block "B" the blue and creme can be different from block "A" or you can keep the all the same in all 24 blocks. Just as long as the blue and creme is the same in its own block. The other squares can be the same or different in each block. Like in Anna6's blocks the blue and cream is the same in that block but her tan could have been all different or the tan can be the same as in her block, that part you can play with as long as the colors are manly. I hope this makes since,
Glad your in I have you down!!
