My sister-in-law S gave me this fabulous quick and easy fix for thongs, to help eke out their oh-so-tragically-short life span for just a little bit longer... if you love wearing thongs as much as I do then this one is a real goodie.
The hole on my old pink pair had enlarged over time, enough for the thong-y bit to start popping out with frequent and very annoying regularity.... In my lifelong scientific observations and road-testing of the humble thong, I have observed that this is the traditional problem spot, the first piece of the apparatus to fail...
S suggested making use of another common and oft-unappreciated little household gadget, the bread-bag closure thing-y
clipping it on over the thong-y bit underneath (please excuse the highly technical terms in use here) and pull it in nice and firm
There is a tiny bit of a hump underfoot but they will be perfectly good for a spare pair...
and your thongs will live on to walk another beach :)
