There is a China shop that I drive past nearly every day. The window display is made up of cheap polyester clothes, and I have never been inside.
But at the moment I am on a quest to do one thing every day that I have never done before, and going into the China shop was a painless option :-).
And what a surprise it was!
The shop is huge, and after the cheap clothes, the cheap handbags and the cheap furniture comes a section with (you guessed it) cheap hardware. I found casters for a fifth of the price of what it costs elsewhere, and went a bit wild.
I also found a whole heap of little wooden boxes with chinese writing on that were destined for the rubbish. On the same heap was an old lid for a metall dustbin.
The Chinese lady thought it was very funny that I wanted all that junk but handed it over gracefully. She even got her son to carry it to the car for me.
Now the cacti babies I keep on finding all over the garden (I have a strong suspicion that this is the work of a certain puppy) have a new home.
If you want to do something similar, just drill holes into the lid with a metall drill bit and screw the casters on.
Have a lovely weekend full of nice surprises :-)
