I recently made this lanyard from beads from my stash, threaded onto repurposed (unused) fishing wire and using a lanyard attachment from an out of date lanyard.
Meanwhile, I had an idea that may or may not be practical and useful. I put some pot pourri into some old socks, tied up the socks and am putting them in my shoes to deoderise them. This may or may not work as well as deoderising insoles but it's worth a try in the meantime. I often find pot pourri on sale in second hand shops, so this is a cheap and easy idea.
You can see another use I've found for old socks here.
