What a great question! Press the crust down on the edges of the jar to form a clean layer. When you start adding cheesecake filling, use a spoon and drop the filling in the center of the jar. Do not try to press it down. Instead, tap the jar to settle the filling down over the crust layer. If you try to press it down with a spoon, parts of the crust will pull up with the spoon and give it a messy appearance. Take the same approach with the cherry topping - place it in the center first to avoid messing the jar edges. Using two spoons to help it along as well so you aren't scraping the sides.
