I first sewed down the main can cover by hand, using a whip stitch. I found if I spaced the stitches farther apart, when I pulled up on the stitch it would pull the fabrics closer together. Once I was done with the main body, I folded under the circle and pinned it to the body fabric. I pinned one side, then the opposite side, to even out the tension and give a snug fit to the padded can bottom.
