I would cut a small branch from a tree you are partial to as always ask the tree's permission to take the branch and return the favor with a gift of water. Remove any small twigs and lightlysand it so that it is smooth. Now I bless and consecrate my wands in a blend of olive oil, lemon oil, and some drops of my own blood mixed in with the oils.I do the ceremony on a night of a full moon. Good luck in your quest, remember when you make your own wand your power is imbued in it, when you bleed it it is bonded to you, and noone else should touch it.
Blessings and peace:
