Making baskets using plants is all dependant on where you live. The climate will have a huge bearing on what you will find growing locally to you.
I live in Melbourne, Australia, which is a temperate climate. The plants I collect will be very different from someone living in the tropics or subtropics. Those of us in colder climates can get basket makers envy when we think of warmer spots, and their plentiful palms and vines. Truth is, there are still a wonderful array of plants you can gather in colder locations.
