I just kinda tweeked the directions a bit. On the first seam going down the side, I stitched at 1/4 inch. Then, when it's turned inside out to do the last seam, I did that one at 1/2 inch. Worked much better for me because if I didn't, I had threads/fabric showing
Plus, I think doing it this way, makes it look better. A serger is nice, but I think the seams look a bit more finished the way this is.
