Hi
For belts, I run two lines with a border tool or a ruler and a swivel knife, but not all that deep. I mark the inside of the belt every half inch with the medium Tandy and Barry King Meanders and do those. I stamp where I can see a hairline between the tool and the cut, the tool slides in and it works pretty well. I do the insides and then can to the outside of the belt without measuring.
Ah heck, I need to get the smaller meander tool from Barry anyhow.
