A schematic is a visual rendering of a knit or crochet piece. Relevant measurements are indicated on the schematic.

A schematic provides the knitter or crocheter with

• an overview of the size and shape of the piece
• a point of reference for determining the fit of a garment
• a template for use in modifying the size of the piece

It’s important to review the schematic before embarking on a project. Using the shape and measurements of the schematic, you can determine whether changes are needed to achieve your desired fit.

An easy way to determine whether modifications to the pattern are needed is to compare the measurements of an existing, well-fitting garment to the measurements shown in the schematic.
