For the slide skip I use a method that I found by myself. I position my hammer on the very edge of the building and swing myself away form the edge. Then when I hit the top of the building I swing back and pull myself up. That is the most important part for me. I think about swinging myself and pulling myself at the same time to achieve maximum swing distance. For the anvil jump I find it easier to be right on the edge so the pot is slanted. For the top hat I jump and then slowly get the hammer on the snow edge and pull myself in. Hope this helps.
