As you can see above, I am showing two ways of start and end of the weavers. You can wedge them or you can tuck them. Tucking the weavers makes the basket look better if not sturdier. Wedging works just as good though and cuts down on time. So its kind of which one you want at the time. However, as the top of the basket gets larger and the ribs further apart tucking becomes necessary.
No problem, WW. Yep. Anybody can do this. As far as barks, leaves, skins and such, just look for any plant that is fibrous. You don't need to know what it is but it is advisable to use gloves and wash your hands off if you don't know what it is.
