Perfect Box Corners Without the Math
Box corners -- the triangular fabric cuts at the base corners of a tote bag or fabric box that create a flat, squared bottom -- are simple in concept but surprisingly prone to inconsistency when measured and cut by hand. A mark that is slightly off-center, a cut that is slightly angled, or measurements that vary between the two corners produce a bag bottom that does not sit perfectly flat. Carol's Box Corners Template solves this by providing the exact template shape needed for consistent, centered, accurate box corner cuts -- position the template at each corner, trace or cut, and the result is geometrically precise box corners every time.
Why a Dedicated Template Makes a Difference
Box corners are one of those bag construction steps where the difference between a good result and a great result is almost entirely determined by the cutting accuracy. A well-made bag with imprecise box corners sits slightly tilted or develops a bottom that is not quite flat. A well-made bag with precisely cut box corners sits perfectly flat and square, with the professional quality that makes the difference between a bag that looks handmade and one that looks custom-crafted. The template delivers that consistency without the measuring overhead.

How Box Corners Work
Fabric box corners are created by pinching the bottom corner of a sewn bag body so the side seam and bottom seam align, then cutting a small triangle at the corner tip at a measured distance from the point. Sewing across the cut creates the box corner seam. The template defines the correct triangle size and position for the desired box depth -- eliminating the need to measure from the corner point by hand each time.
