What you will need:
- Permanent marker, fine point
- Round file, about 3/8" in diameter
- Needle file (half round or triangular)
The Basic Pattern
1). Mark the spine with the marker. Alternate left and right. I used 3/8" (10mm) spacing.
2). Cut semi-circles on the left side every other mark.
3). Cut semi-circles on the right side, every other mark. The cuts must alternate.
4). With the needle file, cut the 'leaves' about 3/32" (2mm) above each big half round.
5). Repeat the leaves on the right side.
6). Carefully shape the lower portions of the big half rounds to smooth the vine.
And now with pictures...
Start by securing the knife in a vise and cleaning the spine with some sandpaper. Make a mark every 10mm (3/8") along the spine.
You should end up with something like this.
Now with the needle file cut the leaves. These are about 3/32" to 1/8" above the large half rounds. I like to use the small half round or triangular needle file for this.
