Very funny Puffs. By the way, the reason I came across the bathroom basin video was because I was doing the exactly the same job so thought I would take a look just to make sure how others did it. This might have been why I found it so funny, maybe other will not.
When it came to cutting out the front section, I ended up checking the measurements about 10 times just so I didn't make the same mistake. To my relief I made a decent job of it..... Measure twice...Cut once....one of the best bits of advice you will ever hear!....
