hai , a new method of back sinew string to a bow?

i am not take the common back sinew method is a good method!

today i join up a lot short sinew strings to longer sinew strings, i can make the length if i want to get !

next step will turn so easy or not, i can lay some long string(fishing strings, thread)so fine to back a bow.

say good luck for tomorrow,do a invocation to all religion's deity :D
