While cleaning out the barn, we found an unused, old garden hose. We re-purposed it to make keychains, and other uses.
To make one, simply cut a portion of the hose with sharp cutting shears, create a hole at the top (I placed one on each side) by piercing it with a sharp ended tool, or versa-tool (on a safe surface, with safety equipment).
Using pliers, slide a key ring or large sturdy slip ring into one hole, and then onto the hole on the opposite side. Add another larger key ring to the one you use attached.
Adding the first ring can be difficult, however these make fun keychains for lawn mowers, sheds, and other outdoor equipment.
