With 40 blocks made I am finally getting it right. I keep forgetting to use a scant 1/4" seam. When I do remember, everything works great. Here's how to make an Exploding Block:
Using two 4" squares (right sides together) sew a scant 1/4" seam on all 4 edges:
Mark an X on the diagonals as shown. Then cut only through one fabric on the X up to the 1/4" seam. Press open:
With right sides together, sew the block just made to a 5" square (using a scant 1/4" seam) around all four edges:
Mark an X on the 5" square, cut only the 5" square on the X and press open:
Here's a very scrappy version. It's made with no planning at all. Just grab what ever fabric is next:
