Good find and I would gladly pay the 10p just to smash them into bits...I hate tiling!

Heat added ☺

I hope is not 10p each :wink:

lol

They also had the tile end strips at 10p each

Use (dry obviously) spaghetti. Nice small gaps, all exactly the same width and easier to pull out once the adhesive has gone off. I worked for a tiler once and that is what he used.

Interesting, but this was probably cheaper.
