Make cooker knobs more visible

Here's are photos of a quick task where I used Sugru to make the markings on my cooker knobs a lot more visible. It's so much easier to check at a glance that the hobs, grill and oven are all off when I shoot out the door to work!

The steps I took were:

Remove, clean and dry the cooker knobsOpen a pack of Sugru snow whiteMake a thin sausage shape and push into the grooveRemove excess with fingerSmooth over with a wet finger, wipe away any excessRepeat for remaining knobsLeave to cure for 24 hours and re-fit
