Just wondering if anyone can put up a good link on how to get the quilted look on buttercream please. Or do you have any advice on how to do it and which tools to use.
You can buy a plastic texture sheet that will do it for you.
You can make marks at the top and the bottom of the tier, then take a skewer and impress the lines in the icing after it's crusted. If it's a meringue buttercream do it when the icing is cold.
