This is my butterfly fitted, it is a large os. It fits larger then Arfy's, for those with bigger babies.
The punched out holes are elastic placement for a chunky thigh baby.
For an elastic that goes all around the leg (for a skinny minnie) use the red dots, and take a 1/2 inch off the "cut on fold" edge.
The back elastic placement is hard to see in this pic but it lines up with the leg elastic for a chunky thigh.
I usually place this on my fabric, trace, flip and trace. As opposed to cutting on the fold.
