It isn’t that difficult but I’d practice first. I teach it and people understand it pretty fast. Just make sure you crumb coat your cake in the same colour as the basket weave. Also it is a technique that requires more icing than usual, so be sure to have lots. And always start at the bottom of the cake to ensure straight lines up to the top. You know the bottom is level but the top might not be, so if you start at the top the lines will lean more and more as you go along and it will be very noticeable.
Good Luck
