I took a class with Susan Cleveland at IQF in Houston, and she does a double-pointed dresden plate, where she sews both the top and bottom of the pieces, then turns and presses both ends. That way, she doesn't have to have a center circle to cover the ends, and she can do curves with sections of her DPs like a drunkard's path. She said that she will SITD from the point where the blades are sewn together at the top to the bottom, then fold the point back and stitch UNDER the point. Then she stitches from the bottom to the top, folds the point back and stitches UNDER the point. This gives her DPs a little more dimension. I've never done a DP, but when I do, I will do it this way. Also, she does her SITD before she quilts, so none of the stitching is seen.
