Bloc Loc - Drunkards Path Set 3x3
Drunkard’s Path Ruler Sets include one grooved ruler and two oversized cutting templates. The grooved ruler ensures the curved seam ends at 2/3rd along two sides of the finished square.
The templates make it easy to rotary cut the shapes! The best part is, they are oversized so that if your pieces aren’t matched as well as they should, the units will be perfectly trimmed with the grooved ruler. Perfecto!
