Miriam, does the Elna Carina take the black plastic type disks same as the Supermatic? If these stitches aren't any good there's no point in me hunting them down. Blancket stitchesof are often just as much for the decorative as the functional aspect of it though. I am looking for a couple of stretch stitch disks and #146 I thought was pretty close to a blanket stitch. Lock stitch machines will never have a real blanket stitch anyhow.
