You can essentially cut all of the pieces the same as for the right-sided tutorial, and also piece together the components such as the wool coat, the ears and the legs. The four components that are different are
1. the tail: The tail is a 2 by 2.75 dark rectangle with 1.25 inch flip triangles of background fabric in the upper left corner and the lower right corner.
2. upper tip of wool coat (next to the sheep's face): the 2 by 2.75 background rectangle has a 1.25 inch flip triangle of dark fabric in the lower right corner.
3. top left wool puff: the sheep has six 2.75 inch square wool puffs with two 1.25 inch flip triangles on one side. However, for one of these puffs, you add a 1.25 inch flip triangle of light fabric to form the sheep's cheek. For this version, you will take the top puff on the left side and add the 1.25 inch flip triangle of light fabric to the upper right corner.
4. largest dark triangle for sheep's side: Add a 1.25 inch flip triangle of the light fabric to the large 4.25 by 5 inch rectangle of dark fabric.
You can find the instructions for the Right-sided Sheep here.
Let's end with the back end. This should get interesting because Buddy is now up on the desk to help if walking on the keyboard can be considered helpful.
For this section, you will want to make sure you added a 1.25 inch square of light fabric to the upper left hand corner of the 4.25 by 5 inch rectangle of dark fabric. Sew the components of the right side of the wool coat together as shown. Then sew the background strips of fabric to either side of the short back leg. Then sew the short back leg section to the 2.75 by 3.5 rectangle of dark fabric. Finally, sew the long back leg to the short back leg section.
Now sew the leg section to the back flank. And then sew on the right side of the woolly coat.
Now you have all four of the major sections of the sheep completed. Sew the sheep's back end to its front end. Then add the eyes section. And finally add the ears section.
