>From your description, it sounds like you might be describing a series of
half hitches.  I don't know if it has a more specific title than that.  If
you wanted to create it on (say) a vertical bundle, you just pass the line
around the back of the bundle then put the working end between the line and
the bundle, and tighten by pulling away from the knots you've already tied. 
Repeat this over and over up (or down) the bundle to get your nice pattern
happening.

A benefit of this knot is that if you pull the working end towards the knots
you've already tied, the knot will slide back, so you can tie each knot
quickly then pull it back to the right position, so you get a nice even run
of loops.

You'll need to secure each end of the line with something that can stand
tension at a sharp angle.  A quick examination of pikiwedia's knots list
suggests something like an icicle hitch or rolling hitch, but they might be
a bit tricky to tie in tight spaces.  I've just tried two half hitches on a
broomstick and it doesn't hold too badly, but I wouldn't guarantee it'll be
safe long term.

As to the line to use, I'd imagine that an office supplies store would
probably have a range of possibilities.
