I would place them left and bottom. Then lay them out how you want them. Add 1.5" strips to the right side of the last block in a row. Add 1.5" strips to the top of the first row of blocks. That is how it was done for my picture. (Done EQ7) You will end up with sashing between all the blocks and a narrow border all around. It's hard to see the top and right side borders in the picture because they are almost white. As an alternate, you could add the right side and top in one long strip after the rest is together. Personally, I like to add the shorter strips - less stretch. Ann
