Ok if I understand this right..
You get an oval, of some unmentioned size... of 4 fabrics.. you lay one down, right side up.. you lay another right side down on top of the first. You sew around one half of that oval. Then you take the unsewn half and fold it back over the sewn half. Then you take another oval fabric and put it on top with right side down, and sew around the OTHER side that you didn't sew previously. Then fold the unsewn side back, then you take the 4th final fabric and lay that right side down, and go all the way around the edge but leaving a gap to turn inside out. Sound about right?
