Why use a swatch?

Stitch, hook or needle size, fiber, gauge, and personal tension can change yarn usage dramatically. Your own swatch captures those variables better than a generic chart.

How the estimate works

Quicklio scales the yarn used in your swatch by the ratio between swatch area and project area, then adds your chosen buffer.

Best for rectangular projects

This version is strongest for blankets, scarves, panels, and other projects whose finished area is reasonably represented by width × height.
