A good tutorial from this site will get you going:

Watch a few Youtube videos on
cable lacing to get the technique down and it will NEVER come undone without cutting it apart. As you tighten, the friction melts a little of the wax which solidifies in the knot, keeping it in place so that you can cut the free ends 1/4" away without worry of them pulling back through. As a bonus, you don't have the sharp edges that come with zip ties that are improperly cut and it just looks awesome when implemented. I would do it as a final dressing up of the wiring once no changes are to be done as it does take some time, but well worth it in my opinion.
This image shows the Mars Hand Lens Imager (MAHLI) on NASA's Curiosity rover with all of the wiring stitched up using waxed lace.

Anyone planning on going into the telecommunication industry dealing with equipment installation directly, particularly sites (POPs, COs, even self-respecting wiring closets), will become very familiar with the "No Zip Ties/Tie Wraps Allowed!" Waxed Lace, or much less frequently if not permanent Velcro/Hook & Loop/Dual Lock, is all that is allowed. I've sometimes stood there and marveled at the lacing skills of some of the cabling installations that were 80+ years old and how beautiful they look and then trying to live up to the same standards in my new cabling for modern gear. We've even left some of the old stuff in place just to show how it should be done.
