Firstly, avoid buying 4 packs. If, however you do end up with the plastic can holders, you can re-use them as plant ties and plant supports in the garden and they can be re-used each year

I found these suggestions on-line at another recycling site:

Plastic Rings (six packs)
Tie together and use as a trellis for roses.
String together into “chicken wire” and erect around the garden so your dog will know that it is off-limits. Support with wooden handles from shovels, brooms, etc.
Make into a hot pad by cutting each ring separate to form a circle. Double-crochet around each ring. Sew the six smaller rings together to form one large circle.

our local off licence collectrs them to reuse

You can make snowflakes out of them. Here is a link to a website that shows you how to di this.

use a lighter to meld them all together and use as a dolphin-catcher

if you do bin these plastic things, please cut them up so an animal can’t get trapped in them. They can kill (the Simpsons and Happy Feet have shown this!)

I use them when I plant tomato vines and it helps with supporting the branches.

After you use pots made of mud don’t throw them because it takes almost 1000 years to form a layer of soil.

As a sock tidy.

i heard of someone who strung these together to make a hammock. not sure how comfortable it was tho…

My mother makes a beach bag out of them…my non-profit is accepting them as donations for this purpose for a fundraiser…anyone who has some in the DC area…we gladly accept
