Hello all… beware..
Clue 5:
..if you plan on using the “alternate method” Bonnie has listed (drawing line on corner squares)..this is at the bottom of instructions..I would wait. You will see that your “2-corner only blocks” look nothing like Bonnie’s photograph of her actual block using her focus fabric.
It looks to me that it will make a difference in the quilt so I emailed her for clarification on the correct measurements for this method. I figured it out but I would prefer the update come from her if she makes one.
