Howdy one and all - newbie member but experienced DIY amateur here - I really should sign up and do some City & Guilds courses one of these days - interested in Electrics (most enjoyable), will do plumbing as a matter of 'have to' but very rewarding when I've succeeded, brickying as and when but prefer to pay a pro, enthusiastic carpenter along the lines of 'functional but **** to look at' - again, prefer to marvel at the work of a true craftsman than 'have a go' myself, but practice makes perfect...
