Depending on the length of your wire bundle, you can work comfortably with a piece of lacing tape up to 10 feet long.
For shorter bundles, start with a piece about 2 or 2 1/2 times the length of the wire run. The length needed will vary with the thickness of the bundle, and the spacing of the stitches.
Start the installation on one end with a locked clove hitch (see instructions at left), leaving most of the length on one end of the knot, and just enough to finish the knot on the other.
Snug the knot tight and trim the short end to about 1/8" or so.
Keeping the lacing tape as flat and free of twists as possible, move down the wire bundle about 4 inches and form a simple lock stitch
Continue along the bundle, repeating the lockstitch at regular intervals.
When you come to the end of the installation, take a couple of extra turns into the lock stitch, and tie the lacing tape off with a square knot. Trim the end, and you're done.
