Step 5- You are done with color 3. Now, you do the same thing with color 4. Using a 1 ½” wide strip of color 4, line up the squares and sew them onto the strip. Press and cut. Then add the other side of color 4 to make it square again after it’s pressed and cut. In the pictures, I’m using the same fabric for color 3 and 4 so I hope I’m not confusing you. Just like doing a log cabin block, you are adding layers. Your finished square after color 4 will measure 3 ½” x 3 ½”.
