Zebranowood is an instructables member and is super nice and helpful if you ask him questions. He has a you tube channel where he shoes a few different techneques (probably also has step by step buides on instructables too ) https://www.youtube.com/channel/UCngHVOU8ZgkDMZKLcl-btDQ/videos?view=0&shelf_id=2&sort=p
