Layer Guides by We R Memory Keepers.
Create perfect borders every time with these layer guides!
The catch-lip system requires no measuring.
The guides have numbers on the top that correspond with the width of the borders.
Easily choose your border width and position the catch-lip against the edge of your project. Next, press firmly on the tool and cut along the edge; you can add additional layers in any of three sizes for added dimension to your craft.
