Sewing the stripes together is not the same technique as is portrayed. The technique discussed inserts the strip then folds it back and top stitches it. You would have to allow more fabric anyway if you were going to do this as one piece.

King talks about the shorter edge of the bias. The bias tape makers make equal edges. Nowhere does he discuss how he arrives at a "shorter edge." When pressing the tape you would have to press it with one edge narrower than the other. This is much like a binding you would apply to a quilt. I am assuming that he feels everyone should know about that technique already.

On the baby hem, I agree that it is very fast, but if you notice the first seam is folded on the seamline then stitched at that point. After trimming, the seam is turned in again and stitched. If you turn it the second time, as I see it, the edge finish will be narrower than intended by one seamline.

A few years ago, I made a very attractive turquoise linen dress. I sewed well having taken many sewing classes but I knew less than nothing about fabrics. Unfortunately I washed the dress and of course it shrank to an unwearable disaster. I saved it for a long time trying to consider what I could use it for, but at that time there was little information about recycling so I ultimately gave it to a charity.

Another technique for a satin stitch corner is a mitered corner.

When near the corner, stop before you reach the end of the corner. The place where you must stop is the measurement that is the width of the original satin stitch. (That is, measure the width of the satin stich and that becomes the length from the corner where you must stop.)

At that point, slowly begin to narrow the width of the satin stich until you reach the narrowest stitch right at the end of the corner. The end of the stitching tapers to a point.

Turn the item 90 degrees. Start the satin stitch, but this time begin with the narrowest stitch and gradually increase the satin stich width until the empty space starting at the point fills in. You don't want the mitering stitches to exceed the empty space. Try it on some scraps and it becomes quite easy. The mitered corner looks like the frame of a picture on the wall, very nice. Pam
