I was down at the grocery store today when I saw under a counter this large twist tie it's about a 1/2' wide with the wire in the middle, I thought this would be real nice for tying trees as opposed to the skinny stuff that we are all used too, I asked someone that was working there but they didn't have a clue about it, has anyone here ever seen this before or know where to get it? 

thanks dave 

Dave, I use these green velcro strips.  They're about a half inch wide (maybe wider), and they're double sided (loop them around and one side of it sticks to the other side of the same piece).  I got it at Home Depot... came in a rolled up single strip, maybe 25 feet to a roll (use scissors to cut to whatever length pieces you want).  (I'm really not sure what the length was, but one roll was all I needed for 50 trees).

I've seen double-width wire twist ties too, encased in plastic with two wires inside.  But I prefer the velcro.

thanks for that information I am going to the Home Depot tomorrow I will pick some up

At home depot you can usually find in garden area hanging up in rolls for a few dollars this green stretchy vinyl type stuff it does not dig into the bark .
Here you can see in picture.

Used to do it the old fashion way and use strips of old tee shirts and elastic tops of my underwear.

As Martin has just mentioned; that was exactly what I had in mind.
Designed for plants (and for an additional stretch - do 2 loops)...

Mind you; I came across (at least) 2 variants - go for the more
expensive darker-green and thicker type.

And if conditions are allowed, do not tie too-tied.
I had some cases that even that 'bit' into the bark - even it is non metallic.

I use this stuff from Home Despot.
