When I do a meandering pattern, I try to get three different shapes in my mind, none of those shapes have more than three loops (or whatever you want to call that shape, maybe a 'u' shape) going in one direction before I change directions. And remember what you see when you have your nose to the needle is not what you see when you look at if from a foot away.
Give it at least one try on a practice 'sandwich' just to figure out your speed, but remember, it will be harder to manhandle a larger piece than that little square.
