Hi, i need to fit new skirting board after fitting wood engineered flooring, i have purchased the skirt and a mitre box. I have never fitted skirting board before and i dont want to make a mess as the skirting is the last part of my job. I only have two corners to cut (internal)i just need to know the method in what order to do it . Ie the measuring and cutting . Any tips would be apreciated .Thanks
