How do I make a raft for the lake?

When Keith decides to build a raft the outline appears on the sand. Stand on it and hit A and on the screen it will show you what part of the raft you are building next, and what materials you need. The materials are logs and rope in differing quantities, but logs can be found around the jungle, reappearing every two days, and every once in a while washed up on the beaches by your cave. Rope is made from vines found in the jungle; bring some home and put them in the corner. (Skye will have made a spot in the back left corner when you first brought home a vine) do so by walking up to the spot and hitting A, sometimes you have to change your angle a few times, just like when you talk to Skye, in order for it to register. Then hit the up and down arrows to transfer vines in and out of your bag. Ask Skye to make rope, and when she tells you she is done you can go "check ropes" again in the corner and hit the left button, then put transfer ropes into your bag with the down arrow. Ropes do not take up space in your bag; in order to see how many you have, open your bag and then hit the x button. This action also shows you how many worms and spices you have collected.
