This is Eileen's block. It's called Swoon.The instructions are pretty involved. She provided the fabric. Some people have a gray background, some have a white background.
Here are the instructions she gave us follow:
Make hsq's from two 3-7/8" squares to make two hsq's (with color 2 and background)
Repeat this process with color 1 and background (make four of those)
Repeat again with color 1 and 2 (make 8 of those)
For the flying geese units, use one of the 6.5X3.5 (color 1) and two background 3.5" squares to make one flying geese unit.
Make four flying geese units with color 1 and background. Make 4 units with color two and background.
From the half square triangles, squares and rectangles make the four corner units.
From the flying geese and rectangles, make the four middle units of the blocks.
