The toughest shape is probably the first (biggest one on right), but if you think of it as an oval with two circles and triangles (legs) with another oval on top, it may simplify matters. Go ahead and draw it first, then use your drawing as a "pattern" for the fabric.
For the cheeks shape, I folded the fabric and cut out a circle, leaving just a small bit connected. When it unfolds you get the eight shape shown here.
