Obviously I could have gone to a hardware store and bought one, but then I would have ended up with a plain little cage which would have done the job but not been particularly attractive. Instead, by expending just a little effort - and using spare materials from other projects - I was able to create a hanging dispenser that actually looks quite nice.
Step 1: Materials
* Galvanised garden wire
* Two wooden beads
* One Ikea kitchen hook
* Outdoor varnish
* Something to shape the wire - I used a bottle of flavoured water.
The Ikea kitchen hook was a leftover from a kitchen project, but if you don't have one you could hang the dispenser from a length of chain, string, paracord... whatever you like.
Step 2: It's a Wrap
I'm afraid I can't tell you how long the piece of wire I used was, because I worked straight from the original spool. I advise you do the same.
