I did just one block to see how it would come together and found that I need to adjust the seam allowance one more tick smaller than 1/4". I like that control on my Viking Sapphire, can move the needle left and right .02 at a time. 1/4" is 1.8, this is done at 2.0 so I need to move it to 2.2. It was slightly smaller than the 9 1/4" it needed to be so I starched and blocked it to stretch it.
I love this color combination but they will all be different.
