I did SID on log cabins like Martina described. On some machines you can semi-automate the procedure of changing stitch length. On my Bernina 440, for instance, I can use stitch #1 for my regular stitch length with zero width (straight stitch), then go to #2 and set it for zero width and the tiny stitches. All I have to do after that is press 1 to get back to the regular stitch, or 2 to go to the tiny stitch. This feature may work differently on other machines, or may not be present at all, but it's very handy if you can use it.
