Just finished painting my skirtings..flippin difficult when you cant bend in the middle! re the gloss - gloss and egg shell are not ideal in pg because of the fumes, ideally stick to low odour emulsions or satinwoods. In a well ventilated room, light some candles at the end of the day, it helps to burn off some of the fumes.
clara I've just done the same - pulled something at the side of bump...prob caused by getting stuck on the floor too many times and having to haul myself up on the step ladder, so delicate!
