I made this sterling silver and labradorite tree about a year ago for a good friend of mine. I decided to put all the pictures I took of making it into one graphic! As you can see, tieing all the branches and roots is the hard part! It takes a long time securing all those ends and making sure they are not going to poke anyone!
