After couching the window in the top house, I decided to do the speckled house as well.
This time I switched to the applique foot #23 and placed the skein of DMC around the head of my machine. I adjusted the width to 1.5. The clear foot makes it much easier to find the corners of the windows.
Block 3 is still missing the head of the cat and a dog. I decided I like the couching around the windows. I wonder if it would be faster by hand than by machine. Hmmmm.
