Sample comments are like a trail of breadcrumbs that marks the path a style has taken so far. If you ever get lost, you can retrace your steps and find your way back to where things went wrong.
The sample comments is a section of a tech pack where you keep records of each sample and change during the development process. Each sample page documents detailed spec measurements, photos, and notes. These pages will not only refresh your memory on decisions made, but help you determine if a pattern, cutting, or sewing change is needed to correct each issue.
This sample comments section is one of the big reasons why I start tech packs early in the development process – far before production. It keeps this breadcrumb trail organized and easy to find.
