Here are the final steps of constructing the block.
The units made last time are sewn together to make the light and dark quadrants of the block. They look like kitties to me, but they also look a lot like my chihuahua with her pointy ears standing at alert attention. If you're not fond of animals, I suppose they could resemble the feathered end of an arrow.
The new seam on both color arrangements is pressed toward the half with the dark square.
(The light kitty above was not being very cooperative about being photographed!)
Now it's time to sew a light quadrant to a dark one. I chose to press this seam toward the dark kitty.
Finally, sew two halves together to complete the block.
I found it easiest to not press this seam, waiting until I sewed the blocks together so that I could finger press the seams in opposite directions when the time came. I'm putting this project aside until January to add borders and such, but I'll try to get a photo of it tomorrow.
