This pattern results in an oak leaf with veins in it.

Use any kind of color you want for this leaf. I added color to it with arcylic paint.

I use 2 types of wires, the thicker one is a stronger wire. I don’t know the name of it, I found it at home.
THe lighter one is a 0.4mm wire for jewels. This one has gold color in it because I mainly used yellow yarn.
