I'll be super fit soon, going up and down a ladder all day. First off was touching up the paint job in the bedroom, then fixing loose paper edges on the ceiling, filling same ceiling, filling cracks in the kitchen walls, sanding and re-filling, lastly undercoating. None of them major jobs but badly needed and long overdue. Re-painting the kitchen walls will be major but luckily we don't have the right paint so I've put that off!
Tip of the day: don't try cooking up a big pot of pilau rice while you're decorating. It just means even more trips up and down that ladder.
