We all learn to appreciate thick trunked, massively tapered trunks in our first years in bonsai. I remember well trying to achieve this look with my trees and failing. I could neither afford nor find material that worked well for this style of bonsai.
In the last number of years I have come to appreciate and cherish trees made from young, thin materials that are relatively easy to find. In many ways these may be considered bunjin, literati or penjing type styles. In any case I hope you like some of them.
