Uneven tacking is used for general basting, for edges that require less control during permanent stitching, and for marking which can be done by long and spaced stitches. For instance, in holding together the lower part of a full skirt, basting the seams for cuffs or holders and things of that sort. This is also known as long and short tacking which is composed of two short stitches followed by a long stitch. The uneven basting stitch is made the same as the even basting stitch except that the stitch on the upper side of the cloth is made about two or three times as long as the stitch on the under side of the cloth.

This will vary from machine to machine with some being simple and others you should be a rocket scientist to use. The stitch width selector is pretty self explanatory. You use it to select the width of the stitch you want to use in a zig zag stitch.
