No unitaskers in my toolkit!
Never overlook the power of nylon tie wraps for bundling stuff up either. Cheap to make mistakes with.
Second that about the "gardening" hook and loop . I bought some to tie back the Dahlias and said "darn, this would work great for other stuff." The best part is that it does not stick as tenacioiusly as standard hook and loop stuff so when you're standing on your head trying to untie something it's not nearly as annoying. Just cut off a bunch, wind it in a tight spiral to overlap 3/4 of the layer below, voila.
If you put a drop of super-runny CA glue (get it at hobby shops) in the right place, it becomes a lot more permanent. Need to be careful not to glue the cable casing unless that's what you wanted but it works.
