I suggest you use the gloves with the bumps, You'll be surprised at the difference they make, They are alot cheaper then the sheet, your talking about. Your first attemp is way better then mine was. The stitching in the back, was a problem I first had and I kept thinking it was the bottom tension( bobbin), But it was the way the fabric was going through, or rather sliding through. I was pushing and pullin, Then I used the gloves and I had better control of the piece. As good as your doing all ready, it won't take you much pratice at all. But please try the gloves, they helped me alot with control of the piece.
