The slick side of freezer paper also works as the fusible will not stick to it. I use my clear pressing sheet to arrange applique pieces so I can then bond them to the fabric I'm applying them to. I place the pattern under the pressing sheet then arrange the pieces on top. When they are as I want them I press them so they more or less stick together. Then take them to the fabric I'm appliqueing them on and press. Then I'm ready to applique.
