Should have took some step by step photos but basically I start at the bottom of the handle and use a pencil to draw around the wood making sure the spacing is roughly the same, I'll rub out bits if they are too off by a lot and redraw. Then I'll cut inbetween the lines and cut the tall parts of the spiral round or you can leave the squared off for a helix look. After that I basically sand and for inside the spiral I'll use something round like a pencil and wrap the sandpaper around that. Next time I'll make a post about it.
