Howdy Tyler & CyberJack, many cheap discount stores sell packs of various cable ties and I imagine they are considerably less than at the major chains.
I use 2.7mm plain round trimmer line with my Kaaz weed whacker and it works very well. I don't bother with that fancy star shaped stuff.
They don't seem to perform as well and when you look at the cross section, they actually use less nylon to produce the same "thickness".
Yes CyberJack, I was chuffed at the simple solution it provided there. I got a multipack in a variety of colours for a song many years ago and have been looking for uses ever since.
